Alberto:

Not a problem. You can add more data to an index even as it is being read by
your application.

HOWEVER, you must close and reopen your IndexReaders before the
newly-indexed data is available to the readers. This is an expensive
operation, so I would close/open the IndexReader judiciously.

NOTE: when you instantiate the IndexWriter, use false for the create
parameter or you'll erase your existing index.

You can also create an index in a *different* directory and then use a
MultiReader or Searcher, but that requires re-compiling your application to
add in the new indexes, and I assume that's not what you want.

I don't know about Spanish support.

Hi, Devinder,

Lucene is agnostic of any database configuration. You need to pull data via
jdbc out, and feed it to Lucene to create an index file, and then use Lucene
API to search on it.

Yes, with a little bit of work, as there is nothing out of the box
for it.

If you store term vectors (or re-analyze the document) you can use
the sample code from my ApacheCon 2005 talk (http://www.cnlp.org/
apachecon2005/, which also covers how to use TermVectors) OR you can
try implementing the new TermVectorMapper functionality in the trunk
version of Lucene.

Cheers,
Grant

I don't understand what you're trying to do with "match extent". Perhaps
a bit more explanation of the problem you're trying to solve would get
you more helpful answers <G>...

First I want to search document which have values c1 then search document which has c1 as one of field value. I know we can use Term Query but is it the way we should do?
Can't we save something like this filedname1: c1-23 and while parsing get c1 and 23 as two fields. I should also able to query filedname1 with range query.
If you can provide your telephone number I can explain the same to you.

Allahbaksh

1) For Lucene's scoring, there's this:

http://lucene.apache.org/java/2_4_0/scoring.html#Scoring

And Lucene in action also describes the scoring formula.

2) It's up to you to build a Lucene document from your content, so you
decide which parts of your content (body, link, meta) become which
fields in Lucene. At that point Lucene's scoring formula kicks in.

Hi,

Why not use PerFieldAnalyzerWrapper to provide the same thing and that's
already available?

Hello - you are on the wrong list, this is Lucene java user, not the Solr user mailing list. But this is what you are looking for:

https://cwiki.apache.org/confluence/display/solr/Uploading+Data+with+Solr+Cell+using+Apache+Tika
https://wiki.apache.org/solr/ExtractingRequestHandler

First is official, second is old but maybe still relevant. Please not this is usually not to be used in production.

Markus
