is it possible to change the way score from different field combine to give final lucene score

Suppose I have two field field1 and field2 and let the score for a query from field1 and field2 are score1 and score2 respectively.now when computing the final lucene score I instead of score1,I want to use some function (f(score1)) of that score.

AW: feedback: Indexing speed improvement lucene 2.2-2.3.1

Hi Ivan, No, we do not use StandardAnalyser or StandardTokenizer. Most data is processed by fTextTokenStream = result = new org.apache.lucene.analysis.WhitespaceTokenizer(reader); result = new ISOLatin2AccentFilter(result); // ISOLatin1AccentFilter modified that ö - oe

AW: Implement a relaxed PhraseQuery?

Hi Cuong , I have written a TolerantPhraseScorer starting with the code from PhraseScorer but I think I have modified it to much to be generally useful. We use it with bigramm clusters and therefore does not need the slop factor for scoring but have a tolerance factor (depending on the length

Re: AW: feedback: Indexing speed improvement lucene 2.2-2.3.1

Ivan can you describe more about your application? The overall time for indexing has gotten much faster in 2.3, but this is assuming things like retrieving a document from its original source, filtering it, etc, are minimal. If you have an application where most of the time is spent

Re: CorruptIndexException with some versions of java

Just to bring closure here: this in fact looks like some sort of JVM hotspot compiler issue, as best we can tell. Running java with -Xbatch (forces up front compilation) prevents (works around) the issue. I've committed some additional assertions to the particular Lucene code (merging

Hi Uwe, Thanks a lot for the code. I'm digging into it now! Cheers, Cuong On Mon, Mar 24, 2008 at 7:41 PM, Uwe Goetzke [EMAIL PROTECTED] wrote: Hi Cuong , I have written a TolerantPhraseScorer starting with the code from PhraseScorer but I think I have modified it to much to be generally

RE: Field values ...

The Id and Phone fields are stored. So I can just do a MatchAllQuery as you suggested. I have read about field selectors on this mailing list but have never used it. Does anyone know where I can find some sample code? Thank you. Date: Sat, 22 Mar 2008 16:03:54 -0700 From: [EMAIL PROTECTED]

Re: is it possible to change the way score from different field combine to give final lucene score

See the FunctionQuery and the org.apache.lucene.search.function package. You can also implement your own query, as it's not clear to me how exactly you want to calculate the score. Essentially, you have your implementation of BooleanQuery, I think. Perhaps more details would help.

Re: how to control the disk size of the indices

Hi Yannis, I don't think there is anything of that sort in Lucene, but this shouldn't be hard to do with a process outside Lucene. Of course. optimizing an index increases its size temporarily, so your external process would have to take that into account and play it safe. You could also set

Re: Multi process writer access to an index

I didn't see the answer to this question. This is Windows-specific. I'm not a Windows user, so I never had this problem, but I believe we've had code to work around this issue in Java Lucene for years now. It could be that Lucene.Net doesn't have that. In any case, it would be best to check
