Recreating SOLR index after a schema change - without having to re-post the data
Hi, We are using solr-server for a large data-set. We need some changes in solr schema.xml (datatype change from integer to sint for few fields). It turns out that the two datatypes (integer and sint) are incompatible and hence we need to re-index SOLR. My question is: Is there any way by which i can just re-create the index files for existing data/documents in solr? (without having to re-post the documents) I searched through many forums and everything seems to say : "I have to re-post ALL documents to solr for re-indexing". Please suggest me a better alternative to achieve my schema-change (I have very large solr-index - sized around 10GB and it will be tough to query the whole data-set, store it somewhere as XMLs and then to repost) -- Thanks, Vanniarajan
Limiting facets for huge data - setting indexed=false in schema.xml
Hello, We are trying to get Solr to work for a really huge parts database. Details of the database - 55 million parts - Totally 3700 properties (facets). But each record will not have value for all properties. - Most of these facets are defined as dynamic fields within the Solr Index We were getting really unacceptable timing while doing faceting/searches on an index created with this database. With only one user using the system, query times are in excess of 1 minute. With more users concurrently using the system, the response times are further high. We thought that by limiting the number of properties that are available for faceting, the performance can be improved. To test this, we enabled only 6 properties for faceting by setting indexed=true (in schema.xml) for only these properties. All other properties which are defined as dynamic properties had indexed=false. The observations after this change : - Index size reduced by a meagre 5 % only - Performance did not improve. Infact during PSR run we observed that it degraded. My questions: - Will reducing the number of facets improve faceting and search performance ? - Is there a better way to reduce the number of facets ? - Will having a large number of properties defined as dynamic fields, reduce performance ? Thank you. Regards Rahul
Re: Using DIH for parallel indexing
Thanks for the revert Noble. A few questions are still open: 1. Can I pass parameters to DIH and be able to use them inside the "query" attribute of an entity inside the data-config file? 2. Can I use the same data-import-handler in someway so that indexing can be carried out in parallel?

it does not use javax.xml because those work on a DOM tree which is
not usable for large xml files.
This only supports a subset of xpath. The supported syntax is given here

Using DIH for parallel indexing
I am using Solr 1.3 and have a few questions regarding DIH: 1. Can I pass parameters to DIH and be able to use them inside the "query" attribute of an entity inside the data-config file? 2. I am indexing some 2 million database records using DIH with 4-5 nested entities (just one level). These subqueries are highly optimized cannot be avoided. Since, DIH processes records sequentially, it takes a lot of time (approximately 3 hours) to re-build the indexes. My question is - Can I use DIH in someway so that indexing can be carried out in parallel? 3. What happens if I "register" multiple DIH's (like dih1, dih2, dih3 ...) with different data-config files inside the same core and run full-import on each of them at the same time? Are the indexes created by each of these (inside the same data directory) merged? Due to my lack of knowledge on Lucene/Solr internals, some of these questions might be funny. Cheers Avlesh

facet sorting by index on sint fields
Hi, I have a field in my schema specified using Where "sint" is specified as follows (the default from schema.xml) When I do a facet on this field using sort=index I always get the values back in lexicographic order. Eg: adding this to a query string... facet=true&facet.field=wordCount&f.wordCount.facet.sort=index gives me 5 2 6 ... Is this a current limitation of solr faceting or am I missing a configuration step somewhere? I couldn't find any notes in the docs about this. Cheers, Simon

That depends on the servlet container. SolrJ GET requests are sent in UTF-8. Some servlet containers such as Tomcat need extra configuration to treat URLs as UTF-8 instead of latin-1, but the standard http://www.ietf.org/rfc/rfc3986.txt clearly specifies UTF-8.

Re: µTorrent indexed as µTorrent
Thanks, Robert. That's exactly what my problem was. Things work find after I make sure that all my processing (index and query) are using UTF-8. FYI, it took me a while to discover that SolrJ by default uses a GET request for query, which uses ISO-8859-1. I had to explicitly use a POST to do query in SolrJ in order to get it to use UTF-8.

Solr/Lucene performance differences on Mac OS X running Tiger vs. Leopard ?
As far as our NOC guys know the machines are approximately the same, aside from the OS. The Leopard machine is running the default 1.5 JVM. And it's possible that some other application or config issues is to blame. Nobody's "blaming" the OS or Lucene, we're just asking around. Searches on Google haven't turned up any reports, so I'm suspecting the issue lies elsewhere. Also I've run on Leopard for months without any performance issues, though I really don't tax anything on my workstation. -- Mark Bennett / New Idea Engineering, Inc. / mbenn...@ideaeng.com Direct: 408-733-0387 / Main: 866-IDEA-ENG / Cell: 408-829-6513

Problem with retrieving field from database using DIH
Hello all, I've been having this issue for a while now. I am indexing a Sybase database. Everything is fantastic, except that there is 1 column that I can never get back. I don't have direct database access via Sybase client, but I was able to extract the data using some Java code. The field is essentially a Last Modified field. In the DB I believe that it is of type long. In the Java program that I have, I am able to retrieve the data that is in that column and put it in a variable of type Long. This is not the case in Solr, however. I set the variable in the schema as required to see why the data is never stored: This is what I get in the Tomcat logs: org.apache.solr.common.SolrException: Document [00069391] missing required field: lastModified at org.apache.solr.update.DocumentBuilder.toDocument(DocumentBuilder.java:292) at org.apache.solr.update.processor.RunUpdateProcessor.processAdd(RunUpdateProcessorFactory.java:59) at org.apache.solr.handler.dataimport.SolrWriter.upload(SolrWriter.java:67) at org.apache.solr.handler.dataimport.DataImportHandler$1.upload(DataImportHandler.java:276) at org.apache.solr.handler.dataimport.DocBuilder.buildDocument(DocBuilder.java:373) at org.apache.solr.handler.dataimport.DocBuilder.doFullDump(DocBuilder.java:224) at org.apache.solr.handler.dataimport.DocBuilder.execute(DocBuilder.java:167) at org.apache.solr.handler.dataimport.DataImporter.doFullImport(DataImporter.java:316) at org.apache.solr.handler.dataimport.DataImporter.runCmd(DataImporter.java:374) at org.apache.solr.handler.dataimport.DataImporter$1.run(DataImporter.java:355) >From what I can gather, it is not finding the data and/or column, and thus cannot populate the required field.

Re: Reasonable number of maxWarming searchers
I recommend, in this case, that you use Solr's autocommit feature (see solrconfig.xml) rather than having your indexing clients issue their own commits. Overlapped searcher warming is just going to be too much of a hit on RAM, and generally unnecessary with autocommit.

Re: Minimum facet length?
Hi Erik, Thanks for the tip. H, well that's a good point, or maybe I will just do the word filtering upfront and store it separately now that I think about it more.

Re: update some index documents after indexing process is done with DIH
Hoss I see what you mean. I am trying to implement a CustomUpdateProcessor
checking out here:
http://wiki.apache.org/solr/UpdateRequestProcessor
What is confusing me now is that I have to implement my logic in
processComit as you said:
>>you'll still need the "double commit" (once so you can see the
>>main changes, and once so the rest of the world can see your
>>modifications) but you can execute them both directly in your
>>processCommit(CommitUpdateCommand)
I have noticed that in the processAdd you have acces to the concrete
SolrInpuntDocument you are going to add:
SolrInputDocument doc = cmd.getSolrInputDocument();
But in processCommit, having access to the core I can get the IndexReader
but I still don't know how to get the IndexWriter and SolrInputDocuments in
there.
My idea is to do something like:
@Override
public void processCommit(CommitUpdateCommand cmd) throws IOException {
//first commit that show me modification
//open and iterate over the reader and create solrDocuments list
//close reader
//openwriter and update the docs in the list
//close writer and second commit that shows my changes to the world
if (next != null)
next.processCommit(cmd);
}
As I understood the process, the commitCommand will be sent to the
DirectUpdateHandler2. that will proper do the commit via
UpdateRequestProcessor.
Am I in the right way? I haven't dealed with CustomUpdateProcessor for
doing something after a commit is executed so I am a bit confused...
Thanks in advance.

Re: NullPointerException in DataImportHandler
It's very easy to write your own entity processor. At least, that is my experience with extending the SQLEntityProcessor to my needs.

Minimum facet length?
Hi, I am exploring the faceted search results of Solr. My query is like this. http://localhost:8983/solr/select?q=*:*&facet=true&facet.field=text&facet.limit=500&facet.prefix=wick If I don't use the prefix, I get back totals for words like 1,a,of,2,3,4. 1 letter/number occurrences in my documents. Its not really useful since all the documents have some free floating single-digit numbers. Is there a way to restrict the word frequency results for a facet based on the length so I can set it to > 3 or is there a better way? thanks, Darren

I tried with:

and
Same ArrayIndex error each time.
Doesn't it use javax.xml then? I was using the complex local-name
expressions to make it namespace-agnostic -- is it agnostic anyway?

Re: SOLR deleted almost everything?
Right, I figured that that's how it should have sorted... which is why I did a range from 0 to 200 That should have worked for my example, but it removed things over 200, which using lexical sorting seems to still be invalid. What's left are things like: 998914 Now, obviously that is expected, as it starts with a number over 2 but why would things like 2165979 be deleted when that is lexically after 200? Unless... oh man, I hope I didn't put an extra zero in there by accident !! ** checking .bash_history... Oh crap... I ran it between 0 and 7 at some point sigh.

Re: NullPointerException in DataImportHandler
Hi Andrew,
my experience with XPathEntityProcessor is non-existent. ;-)
Just after a quick look at the method that throws the exception:
private void addField0(String xpath, String name, boolean multiValued,
boolean isRecord) {
List paths = new
LinkedList(Arrays.asList(xpath.split("/")));
if ("".equals(paths.get(0).trim()))
paths.remove(0);
rootNode.build(paths, name, multiValued, isRecord);
}
and your foreach attribute value in combination with the xpath:
> forEach="/">
> >
xpath="//*[local-name()='structCategory']/*[local-name()='struct']/*[local-name()='title']"
> />
I would guess that the double slash at the beginning is not working with
your foreach regex. I don't know whether this is something the processor
should expect and handle correctly or whether you have to take care of
in your configuration.
Cheers,
Chantal

Thanks -- I was also missing a forEach expression -- in my case, just "/"
since each XML file contains the information for no more than one document.
However, I'm now getting a different exception:

Re: Posting Word documents
Look again at ExtractingRequestHandler. I havn't looked at what post.jar does internally, but it probably doesn't work with ExtractingRequestHandler unless you can send other params as well. I would use curl as the examples in the doc for ExtractingRequestHandler does. Or figure out if post.jar will work for you and use it correctly. What Handler is 'update..' mapped to? If its not mapped to ExtractingRequestHandler than you have no hope of this working in any case.

Re: NullPointerException in DataImportHandler
Hi Andrew,
your inner entity uses an XML type datasource. The default entity
processor is the SQL one, however.
For your inner entity, you have to specify the correct entity processor
explicitly. You do that by adding the attribute "processor", and the
value is the classname of the processor you want to use.
e.g. processor="XPathEntityProcessor"
(See the wikipedia example on the DataImportHandler wiki page.)
Cheers,
Chantal

Posting data in JSON
Hi All, I'm wondering if it's possible to post documents to solr in JSON format. JSON is much faster than XML to get the queries results, so I think it'd be great to be able to post data in JSON to speed up the indexing and lower the network load. All the best !

I'm pretty sure you can use multiValued string fields in the way you are describing. If you just do a query without the boost do documents with multiple values come back?

Range Query question
Hi, I have a set of XML data that holds Minimum and Maximum values and I need to be able to do specific range queries against them. (Note that this is a contrived example, and that in reality the garage would probably hold all the individual prices of all its cars, but this is analogous to the problem we have which is couched in terms that would obscure the problem.) For example, the following XML fragment is indexed so that each element becomes a Solr document: Ford Ka garage1 2000 4000 garage2 8000 1 I want to be able do a range query where search min value = 2500 search max value = 3500 This should return garage1 as potentially having cars in my price range as the range of prices for the garage contains the range I have input. It's also worth noting that we can't simply look for min prices that fall inside our range or max prices that fall inside our range, as in the case outlined above, none of the individual values fall inside our range, but there is overlap. The problem is that the indexed form of this XML is flattened so the entity has 2 garage names, 2 min values and 2 max values, but the grouping between the garage name and it's min and max values is lost. The danger is that we end up doing a comparison of the min-of-the-mins and the max-of-the-maxes, which tells us that a car is available in the price range which may not be true if garage1 has all cars below our search range and garage2 has all cars above our search range, e.g. if our search range is 5000-6000 then we should get no match. We wanted to include the garage name as an attritube of the min/max values to maintain this link, but couldn't find a way to do this. Finally, it would be extremely difficult for us to modify the XML presented to our system, hence our approach to date. Has anyone had a similar problem and if so how did you overcome it?

On Jul 29, 2009, at 2:38 PM, Mike wrote: Hi, We're using Lucid Imagination's LucidWorks Solr 1.3 and we have a requirement to implement multiple-select faceting where the facet cells show up as checkboxes and despite checked options, all of the options continue to persist with counts. The best example I found is the search on Lucid Imagination's site: http://www.lucidimagination.com/search/ It appears the Solr 1.4 release has support for doing this with filter tagging (http://wiki.apache.org/solr/SimpleFacetParameters#head-f277d409b221b407d9c5430f552bf40ee6185c4c ), but I was wondering if there was another way to accomplish this in 1.3? The only way I can think to do this is to backport the patch to 1.3. FWIW, we are running 1.4-dev at /search, which is where that functionality comes from. -Grant

Indeed, or enclose the text in CDATA tags which should work as well.

Skipping fields from XML
Hi, I want to index a perfectly good solr XML-file into an Solr/Lucene instance. The problem is that the XML has many fields that I don't want to be indexed. I tried to index the file but Solr gives me an error because the XML contains fields that I have not declared in my schema.xml How can I tell Solr to skip unwanted fields and only index the fields that I have declared in my schema.xml?
