Everything in the patch is relative to the trunk directory. * The changes Peter Karich made to DocSetScoreCollector and NonAdjacentDocumentCollapserTest that make it much more memory efficient. * The change Yonik suggested to make field collapsing more efficient. bq. efficiency: the treeset and hashmap are both only the size of the top number of docs we are looking at (10 for instance) We will now have the top 10 documents collapsed by the right field with a collapseCount of 1. Put another way, we have the top 10 groups. This also means that the total count of a search with field collapsing does not represent all the found documents.

# Changed DistributedFieldCollapsingIntegrationTest to use
BaseDistributedSearchTestCase. This fails right now. I believe there is a bug
with the distributed implementation. The distributed version returns one extra
group when compared to the non-distributed version. I've put an @Ignore
annotation on that test.
We can consider creating the functions through a factory so that they can
accept initialization parameters. The schema-fieldcollapse.xml and
solrconfig-fieldcollapse.xml are no longer necessary and can be removed.
Next steps:
# Let us open issues for all the modifications needed in Solr to support this
feature. That will help us break down this patch into more manageable (and
easily reviewable) pieces. I guess we need one for providing custom Collectors
for SolrIndexSearcher methods. Any others?
# The response format is not very clear in the wiki. We should add more
examples and explain the format.

Used in order to collapse a group of results with similar value for a given
field to a single entry in the result set. Site collapsing is a special case
of this, where all results for a given web site is collapsed into one or two
entries in the result set, typically with an associated more documents from
this site link. See also Duplicate detection.

The field collapseCollectorFactories in CollapseComponent was null when not specifying any collapse collector factories in the solrconfig.xml which resulted in a NPE. # Removed a system.out that I accidentally added in my previous patch. The DistributedFieldCollapsingIntegrationTest is still failing, because you left out changes in JettySolrRunner, CoreContainer and SolrDispatchFilter from my original patch. That allowed my the specify different schema file for this particular test. I think it is important for the test coverage to have this test. Should I add the fields of the schema-fieldcollapse.xml to the schema.xml that the other tests use? The test should then succeed.

Due to changes in the trunk applying the previous patch will result into merge conflicts. The new patch can be applied without merge conflicts.

The result of that was that the collapsing algorithm could not properly group the documents into the collapse groups (the most relevant document per document group could not be determined properly), because there was not score information when retrieving the documents from cache (as DocSet in SolrIndexSearcher) . I made sure that in the attached patch the score is also saved in the cache, so the collapsing algorithm can do its work properly when the documents are retrieved from the cache. Because the scores are now stored with the cached documents the actual size of the filterCache in memory will increase.

Attachment: field-collapse-5.patch
I have attached a new patch which includes a major refactoring which makes the
code more flexible and cleaner. The patch also includes a new aggregate
functionality and a bug fix.
h3. Aggregate function and bug fix
The new patch allows you to execute aggregate functions on the collapsed
documents (for example sum the stock amount or calculating the minimum price of
a collapsed group). Currently there are four aggregate functions available:
sum(), min(), max() and avg(). To execute one or more functions the
_collapse.aggregate_ parameter has to be added to the request url. The
parameter expects the following syntax: _function_name(field_name)[,
function_name(field_name)]_. For example: collapse.aggregate=sum(stock),
min(price) and might have a result like this:
{code:xml}
lst name=aggregatedResults
lst name=sum(stock)
str name=Amsterdam10/str
...
/lst
lst name=min(price)
str name=Amsterdam5.99/str
...
/lst
/lst
{code}
The patch also fixes a bug inside the {{NonAdjacentDocumentCollapser}} that was
reported on the solr-user mailing list a few days ago. An index out of bounds
exception was thrown when documents were removed from an index and a field
collapse search was done afterwards.
h3. Code refactoring
The code refactoring includes the following things:
* The notion of a {{CollapseGroup}}. A collapse group defines what an unique
group is in the search result. For the adjacent and non adjacent document
collapser this is different. For adjacent field collapsing a group is defined
by its field value and the document id of the most relevant document in that
group. More then one collapse group may have the same fieldvalue. For normal
field collapsing (non adjacent) the group is defined just by the field value.
* The notion of a {{CollapseCollector}} that receives the collapsed documents
from a {{DocumentCollector}} and does something with it. For example keeps a
count of how many documents were collapsed per collapse group or computes an
average of a certain field like price. As you can see in the code instead of
using field values or document ids a collapse group is used for identifying a
collapse group.
{code}
/**
* A codeCollapseCollector/code is responsible for receiving collapse
callbacks from the codeDocumentCollapser/code.
* An implementation can choose what to do with the received callbacks and
data. Whatever an implementation collects it
* is responsible for adding its results to the response.
*
* Implementation of this interface don't need to be thread safe!
*/
public interface CollapseCollector {
/**
* Informs the codeCollapseCollector/code that a document has been
collapsed under the specified collapseGroup.
*
* @param docId The id of the document that has been collasped
* @param collapseGroup The collapse group the docId has been collapsed under
* @param collapseContext The collapse context
*/
void documentCollapsed(int docId, CollapseGroup collapseGroup,
CollapseContext collapseContext);
/**
* Informs the codeCollapseCollector/code about the document head.
* The document head is the most relevant id for the specified collapseGroup.
*
* @param docHeadId The identifier of the document head
* @param collapseGroup The collapse group of the document head
* @param collapseContext The collapse context
*/
void documentHead(int docHeadId, CollapseGroup collapseGroup, CollapseContext
collapseContext);
/**
* Adds the codeCollapseCollector/code implementation specific result
data to the result.
*
* @param result The response result
* @param docs The documents to be added to the response
* @param collapseContext The collapse context
*/
void getResult(NamedList result, DocList docs, CollapseContext
collapseContext);
}
{code}
There is also a {{CollapseContext}} that allows you store data that can be
shared between {{CollapseCollectors}}.
* A {{CollapseCollectorFactory}} is responsible for creating a
{{CollepseCollector}}. It does this based on the {{SolrQueryRequest}}. All the
logic for when to enable a certain {{CollapseCollector}} must be placed in the
factory.
{code}
/**
* A concrete codeCollapseCollectorFactory/code implementation is
responsible for creating {...@link CollapseCollector}
* instances based on the {...@link SolrQueryRequest}.
*/
public interface CollapseCollectorFactory {
/**
* Creates an instance of a CollapseCollector specified by the concrete
subclass.
* The concrete subclass decides based on the specified request if an new
instance has to be created and
* can return codenull/code for that matter.

Attachment: field-collapse-5.patch
I have created a new patch that has the following changes:
1) Non adajacent collasping with sorting on score also uses the Solr caches
now. So now every field collapse searches are using the Solr caches properly.
This was not the case in my previous versions of the patch. This improvement
will make field collapsing perform better and reduce the query time for regular
searches. The downside was, that in order to make this work I had to modify
some methods in the SolrIndexSearcher.
When sorting on score the non adjacent collapsing algorithm needs the score per
document. The score is collected in a Lucene collector. The previous version of
the patch uses the searcher.search(Query, Filter, Collector) method to collect
the documents (as a DocSet) and scores, but by using this method the Solr
caches were ignored.
The methods that return a DocSet in the SolrIndexSearcher do not offer the
ability the specify your own collector. I changed that so you can specify your
own collector and still benefit from the Solr caches. I did this in a non
intrusive manner, so that nothing changes for existing code that uses the
normal versions of these methods.
{code}
public DocSet getDocSet(Query query) throws IOException {
DocSetCollector collector = new DocSetCollector(maxDoc()6, maxDoc());
return getDocSet(query, collector);
}
public DocSet getDocSet(Query query, DocSetAwareCollector collector) throws
IOException {
}
DocSet getPositiveDocSet(Query q) throws IOException {
DocSetCollector collector = new DocSetCollector(maxDoc()6, maxDoc());
return getPositiveDocSet(q, collector);
}
DocSet getPositiveDocSet(Query q, DocSetAwareCollector collector) throws
IOException {
.
}
public DocSet getDocSet(ListQuery queries) throws IOException {
DocSetCollector collector = new DocSetCollector(maxDoc()6, maxDoc());
return getDocSet(queries, collector);
}
public DocSet getDocSet(ListQuery queries, DocSetAwareCollector collector)
throws IOException {
...
}
protected DocSet getDocSetNC(Query query, DocSet filter) throws IOException {
DocSetCollector collector = new DocSetCollector(maxDoc()6, maxDoc());
return getDocSetNC(query, filter, collector);
}
protected DocSet getDocSetNC(Query query, DocSet filter, DocSetAwareCollector
collector) throws IOException {
.
}
{code}
I also made a DocSetAwareCollector that both DocSetCollector and
DocSetScoreCollector implement.
2) The collapse.includeCollapsedDocs parameters has been removed. In order to
include the collapsed documents the parameter collapse.includeCollapsedDocs.fl
must be specified. collapse.includeCollapsedDocs.fl=* will include all fields
of the collapsed documents and collapse.includeCollapsedDocs.fl=id,name will
only include the id and name field of the collapsed documents.

Attachment: field-collapse-5.patch
Hi Thomas, I have fixed the problem and updated the patch. I was able to
reproduce the bug on the Solr example dataset. The problem was not limited to
field collapsing with sorting on a field alone. The problem was located in the
NonAdjactentFieldCollapser in the doCollapse(...) method in this specific part:
{code}
// dropoutId has a value smaller than the smallest value in the queue and
therefore it was removed from the queue
collapseDoc.priorityQueue.insertWithOverflow(currentId);
// check if we have reached the collapse threshold, if so start counting
collapsed documents
if (++collapseDoc.totalCount collapseTreshold) {
collapseDoc.collapsedDocuments++;
if (dropOutId != null) {
addCollapsedDoc(currentId, currentValue);
}
}
{code}
Lets say that that the currentId has the most relevent field value and the
collapseThreshold is met. When the currentId is added to the queue it stays
there and another document id will be dropped out. In this situation a document
that is the most relevant field value is added to the collapsed documents and
it stays in the queue and therefore it will also be added to the normal
results.
I changed it to this.
{code}
// dropoutId has a value smaller than the smallest value in the queue and
therefore it was removed from the queue
Integer dropOutId = (Integer)
collapseDoc.priorityQueue.insertWithOverflow(currentId);
// check if we have reached the collapse threshold, if so start counting
collapsed documents
if (++collapseDoc.totalCount collapseTreshold) {
collapseDoc.collapsedDocuments++;
if (dropOutId != null) {
addCollapsedDoc(dropOutId, currentValue);
}
}
{code}
Now only a document that will never and up in the final results is added to the
collapsed documents (and not the current document that might be more relevant
then other documents in the priority queue). The above code change fixes the
bug in my test setups, can you also confirm that this fixes the issue on your
side?

Attachment: field-collapse-5.patch
I have updated the field collapse patch with the following:
1. Added the return collapse documents feature. When the parameter
_collapse.includeCollapsedDocs_ with value true is specified then the collapsed
documents will returned per distinct field value. When this feature is enabled
a collapsedDocs element is added to the field collapse response part. It looks
like this:
{code:xml}
lst name=collapsedDocs
result name=Amsterdam numFound=2 start=0
doc
str name=id262701/str
str name=titleBitterzoet, 100% Halal, Appletree Records amp; Deux
d'Amsterdam presents/str
/doc
doc
str name=id327511/str
str name=titleSalsa Danscafé/str
/doc
/result
/lst
{code}
It is also possible to return only specific fields with the
_collapse.includeCollapsedDocs.fl_ parameter. It expects fieldnames delimited
by comma, just like the normal fl parameter.
These feature can dramatically impact the performance, because a group can
potently contain many documents which all have to retrieved from the index and
transported over the wire. So it is certainly wise to use it in combination
with the fl parameter.
2. Added Solrj support for collapsed documents feature.
3. Added the performance improvements that Abdul suggested.
4. The debug information is now *not* returned by default. When the parameter
_collapse.debug_ with value true is specified, then the debug information is
returned.
5. When field collapsing is done on a field that is multivalued or tokenized
then an exception is thrown. I have chosen to do this because collapsing on
such fields lead to unexpected results. For example when a field is tokenized
only the last token of the field can be retrieved from the fieldcache (the
fieldcache is used for retrieving the fields from the index in a cached manner
for grouping documents into groups of distinct field values). This results in
collapsing only on the last token of a field value instead of the complete
field value. Multivalued fields have similar behaviour, plus for multivalued
fields the Lucene FieldCache throws an exception when there are more tokens for
a field than documents. Personally I think that throwing an exception is better
then have unexpected results, at least it is clear that something field
collapse related is wrong.
6. When doing a normal field collapse and not sorting on score the Solr caching
mechanism is used. Unfortunately this was previously not the case.
@Paul
When doing non adjacent collapsing (aka normal collapsing) the Solr caches are
not being used. The current patch uses the Solr caches when doing a search
without scoring, but still the most common case is of course field collapsing
and sorting on score. This is because the non adjacent field collapse algorithm
requires the score of all results, which is collected with a Lucene collector.
The search method on the SolrIndexSearcher that specifies a collector, does not
have caching capabilities. In the next patch I will fix this problem, so that
normal field collapse search uses the Solr caches as they should. The adjacent
collapsing algorithm *does* use the solr caches, but the algorithm is much
slower than non adjacent collapsing.

Attachment: field-collapse-5.patch
I have updated the field collapse patch and made the following changes:
# Refactored the collapse code into a strategy pattern. The two distinct
manners of collapsing are now in two different classes, which in my
understanding makes the code cleaner and easier to understand. I have removed
the {{CollapseFilter}} and created a {{DocumentCollapser}} which is an
interface. The {{DocumentCollapser}} has two concrete implementation the
{{AdjacentDocumentCollapser}} and the {{NonAdjacentDocumentCollapser}}. Both
implementation share the same abstract base class {{AbstractDocumentCollapser}}
that has fields and methods that are common in both concrete implementation.
# Removed deprecated Lucene methods in the {{PredefinedScorer}}.
# Fixed a normal field collapse bug. Filter queries were handled as normal
queries (were added together via a boolean query), and thus were also used for
scoring.
# Added more unit and integration tests, including two tests that tests facets
in combination with field collapsing. These tests test the collapse before
collapsing and after collapsing.
This patch only works with the Solr 1.4-dev from revision 804700 and later.

Use this patch for rev 801872 and up. For revisions before that use the older patches. I have also included SolrJ support for fieldcollapsing in this patch. Might be handy those integrating with Solr via SolrJ. By invoking enableFieldCollapsing(...) with a fieldname as parameter on SolrQuery class you enable fieldcollapsing for the current request.

I tested it with an index 1.1 million documents. When collapsing on all documents and with no sorting specified (so sorting on score) the query time is around 130ms compared with the previous patch which is around 1.5 s. When I then add sorting on string field the query time is around 220 ms compared with the previous patch which is around 5.2 s. The reason why it is faster is because the latest patch queries for a doclist instead of a docset. In the normal collapse method it keeps track of the most relevant documents, so the end result is the same, also creating a docList of 1.1 million documents (and ordering it) is very expensive. Note: I did not improved adjacent collapsing, because the adjacent method needs (as far as I understand it) a completely sorted list of documents (docList). 2) Sightly improved facetation in combination with field collapsing, by reusing the uncollapsed docset that is created during the collapsing process (the previous patch made invoked a second search). I also have added documentation, added a few unit tests for the collapsing process itself and made the debug information easier readable. I'm very interested in other people's experiences with this patch and feedback on the patch itself.

[ https://issues.apache.org/jira/browse/SOLR-236?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] dieter grad updated SOLR-236: - Attachment: collapsing-patch-to-1.3.0-dieter.patch I had to make a patch to fix two issues that we needed for our system. I am not used to this code, so maybe someone can pick this patch and make it something useful for everybody. The fixes are: 1) When collapsing.facet=before, only the collapsed documents are returned (and not the whole collection). 2) When collapsing is normal, the selected sort order is preserved by returning the first document of the collapsed group. For example, if the values of the collapsing field are: 1) Y 2) X 3) X 4) Y 5)X 6)Z the documents returned are 1, 2 and 6, in that order. So, for example, if you sort by price ascending, you will get the result sorted by price, where each item is the cheapest item of its collapsed group.

[ https://issues.apache.org/jira/browse/SOLR-236?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Karsten Sperling updated SOLR-236: -- Attachment: field-collapsing-extended-592129.patch I've done some work on the field collapsing patch and made some additions and changes and posting this patch (against revision 592129) here for discussion. - Added a collapse.facet = before|after parameter to control if faceting happens before or after collapsing. - Changed collapse.max to collapse.threshold -- this value controls after which number of collapsible hits collapsing actually kicks in (collapse.max is still supported as an alias). - Added a collapse.maxdocs parameter that limits the number of documents that CollapseFilter will process to create the filter DocSet. The intention of this is to be able to limit the time collapsing will take for very large result sets (obviously at the expense of accurate collapsing in those cases). - Inverted the logic of the filter DocSet created by CollapseFilter to contain the documents that are to be collapsed instead of the ones that are to be kept. Without this collapse.maxdocs doesn't work. - Added collapse.info.doc and collapse.info.count parameters to provide more control over what gets returned in the collapse_counts extra results. - Made a minimal change to SolrIndexSearcher.getDocListC() to support passing both the filter and filterList parameters. In most cases this was already handled anyway. - Did some general refactoring and added comments and a test case. If somebody with deeper Solr/Lucene knowledge could review these changes it would be much appreciated.
