Re: Ranking result on the basis of field value irrespective of score
Create your languages field (or a copy) in such a way that sort gives you the order you want. Then just query Solr with sort=language asc parameter. 2008/10/23 Amit [EMAIL PROTECTED] Hi All, How we can do the ranking on the basis of specific field value irrespective of score in solr? For example: Let say field language which content values like German,English,French,Chines,Arabic. So I want English language document come first irrespective of score.

Re: delta-import for XML files, Solr statistics
On Fri, Oct 24, 2008 at 5:14 PM, [EMAIL PROTECTED] wrote:
Hello,
I have some questions about DataImportHandler and Solr statistics...
1.)
I'm using the DataImportHandler for creating my Lucene index from XML files:
###
$ cat data-config.xml
dataConfig
dataSource type=FileDataSource /
document
entity name=xmlFile
processor=FileListEntityProcessor
baseDir=/tmp/files
fileName=myDoc_.*\.xml
newerThan='NOW-30DAYS'
recursive=false
rootEntity=false
dataSource=null
entity name=myDoc
url=${xmlFile.fileAbsolutePath}
processor=XPathEntityProcessor
forEach=/myDoc
...
/dataConfig
###
No problems with this configuration - All works fine for full-imports, but...
=== What means 'rootEntity=false' and 'dataSource=null'?
It is a menace caused by 'sensible defaults'
An entity directly under the document is a root entity. That means
that for each row emitted by the root entity one document is created
in Solr/Lucene . but as in this case we do not wish to make one
document per file. we wish to make one document per row emitted by the
entity 'myDoc' .Because the entity 'xmlFile' is not has
rootEntity=false the entity directly under it becomes a root entity
automatically and each row emitted by that becomes a document.
In most of the cases there is only one datasource (A JdbcDataSource)
and all entities just use them . So it is an overkill to ask them to
write the datSource. So we have chosen to implicitly assign the
datasource with no name to that entity. But in case of
FileListEntityProcessor a datasource is not necessary . But it won't
hurt even if you do not put dataSource=null . It just means that we
won't create a DataSource instance for that.
2.)
The documentation from DataImportHandler describes the index update process
for SQL databases only...
My scenario:
- My application creates, deletes and modifies files from /tmp/files every
night.
- delta-import / DataImportHandler should mirror _all_ this changes to my
lucene index (= create, delete, update documents).
The only Entityprocessor which supports delta is SqlEntityProcessor.
The XPathEntityProcessor has not implemented it , because we do not
know of a consistent way of finding deltas for XML. So ,
unfortunately,no delta support for XML. But that said you can
implement those methods in XPathEntityProcessor . The methods are
explained in EntityProcessor.java. if you have questions specific to
this I can help.Probably we can contribute it back
=== Is this possible with delta-import / DataImportHandler?
=== If not: Do you have any suggestions on how to do this?
3.)
My scenario:
- /tmp/files contains 682 'myDoc_.*\.xml' XML files.
- Each XML file contains 12 XML elements (e.g. titlefoo/title).
- DataImportHandler transfer only 5 from this 12 elements to the lucene index.
I don't understand the output from 'solr/dataimport' (= status):
###
response
...
lst name=statusMessages
str name=Total Requests made to DataSource0/str
str name=Total Rows Fetched1363/str
str name=Total Documents Skipped0/str
str name=Full Dump Started2008-10-24 13:19:03/str
str name=

str name=Committed2008-10-24 13:19:05/str
str name=Optimized2008-10-24 13:19:05/str
str name=Time taken 0:0:2.648/str
/lst
...
/response
=== What is Total Rows Fetched rsp. what is a row in a XML file? An
element? Why 1363?
=== Why shows the Added/Updated counter 681 and not 682?
rows fethed makes a lot of sense with SqlEntityProcessor. It is the
no:of rows fetched from DB . It is the cumulative no:of rows given out
by all entitiies put together. in your case it will be the total files
+ total rows emitted from the xml
Added updated is the no:of docs . How do you know the number is not accurate?
4.)
And my last questions about Solr statistics/informations...
=== Is it possible to get informations (number of indexed documents, stored
values from documents etc.) from the current lucene index?
=== The admin webinterface shows 'numDocs' and 'maxDoc' in
'statistics/core'. Is 'numDocs' = number of indexed documents? What means
'maxDocs'?
Thanks a lot!

Deadlock problem on searcher at warm up.
Hi everyone,
I'm implementing a search component inherited from SearchComponent .
This component has to build a data structure from the index. Like in
the SpellChecker, I trigger this building by giving a special argument
at query time (from the process method) and I'm using the searcher I
get like this:
RefCountedSolrIndexSearcher search = rb.req.getCore()
.getSearcher();
...
search.decref();
I included this component at the end of the chain in my search handler.
What I'd like to do is to trigger this building for a first time at
solr startup so I don't need to artificially trigger it for a first
time.
I though it'd be ok to trigger this the very first time the process
method is called by doing something like that:
private boolean firstTime= true ;
public void process(ResponseBuilder rb) throws IOException {
if ( firstTime ){
firstTime = false ;
buildMyStuff(rb) ;
}
}
The problem is that my method buildMyStuff hangs when calling
rb.req.getCore().getSearcher() ; ,
and I believe this is happening when the warm up queries are executed.
Furthermore, any regular queries on a solr instance like this would
hang and wait forever.
I there any way I can get around this problem, or is there a better
way to buildMyStuff a first time when solr is started up?
Cheers,
Jerome.

Re: customizing results in StandardQueryHandler
I'm still not following... Does the logic depend on the result? That is, are you asking for doc A to have f1,f2 and doc B to have f1,f4? If that is your question, then no -- as is, the ResponseWriter will write the same fields for every document. When you say (f2, f3, and some new data) -- where does the new data come from? Are you trying to augment the results of a document with something else? If so, take a look at the local solr patch in: https://issues.apache.org/jira/browse/LUCENE-1387 that adds a distance calculation to each matched document.

Do you have enough memory to do that? Typically DBs like as much mem as they can get, as does Solr (for the most part). That being said, 100K records is next to nothing, so I doubt Solr is taking that much memory. Please describe a bit more what you are doing and seeing.

When doing large updates of records via solr sharp, solr completely freezes and doesn’t come back until we restart tomcat. This has only started happening since putting mysql on the same box (as a source of the data to update from). Are there any known issues with running solr and mysql on the same box? When it’s frozen, the cpu usage is around 1-2% not exactly out of resources! Am i best using something else instead of tomcat? We’re still trialling solr (presently, used for our main site search www.shoe-shop.com and search and navigation for our microsites ). It’s an excellent search product, but I don’t want to fork out on new hardware for it just yet – until i know how more about the performance and which environment i’m best to go for (win/linux).

Entity extraction?
During a recent sales pitch to my company by FAST, they mentioned entity extraction. I'd never heard of it before, but they described it as basically recognizing people/places/things in documents being indexed and then being able to do faceting on this data at query time. Does anything like this already exist in SOLR? If not, I'm not opposed to developing it myself, but I could use some pointers on where to start. Thanks, - Charlie
RE: customizing results in StandardQueryHandler
Populating the field at the index time is a good option. Is there any other way to do it in search time Thanks, Kalyan Manepalli -Original Message- From: Ryan McKinley [mailto:[EMAIL PROTECTED] Sent: Friday, October 24, 2008 2:14 PM To: solr-user@lucene.apache.org Subject: Re: customizing results in StandardQueryHandler I'm still not following... Does the logic depend on the result? That is, are you asking for doc A to have f1,f2 and doc B to have f1,f4? If that is your question, then no -- as is, the ResponseWriter will write the same fields for every document. When you say (f2, f3, and some new data) -- where does the new data come from? Are you trying to augment the results of a document with something else? If so, take a look at the local solr patch in: https://issues.apache.org/jira/browse/LUCENE-1387 that adds a distance calculation to each matched document.

Re: Entity extraction?
This is not something solr does currently...

RE: Solr 1.3 stack overflow when accessing solr/admin page
I am running the packaged war.

Index partitioning
Hi, I want to partition my index based on category information. Also, while indexing I want to store particular category data to corresponding index partition. In the same way I need to search for category information on corresponding partition.. I found some information on wiki link http://wiki.apache.org/solr/IndexPartitioning. But it couldn't help much in implementation. Could some one give example with how I can configure, index data into particular partitions and search on particular partition. Would appreciate for any help!! Thanks Regards, Mahendra
