Default sort order with identical scores.

I want to run a query where all the results would have the identical score of 1.0 (all documents of type X with a date D) The trick is that i need to get the result set BACK sorted by the date. The Lucene filter mechanism is optimized to use the index but the only problem is that I want to

Re: AND instead OR for the search

I tried this before with 1.3rc1. The query parser still uses OR rather than AND as default even after I set the operator to AND. I found this issue had been reported before but no answer for it. http://nagoya.apache.org/eyebrowse/[EMAIL PROTECTED] he.orgmsgId=710724 Any idea to solve the issue?

Re: AND instead OR for the search

so, I pasted in the code given in an earlier email: QueryParser qp = new QueryParser(content, analyzer); qp.setOperator(QueryParser.DEFAULT_OPERATOR_AND); query = qp.parse(queryString); it compiles, but it can't find anything. when I comment that out and put in the vanilla call to parse, then

lucene scoring algorithm

Hi, I'm trying to understand the scoring algorithm of lucene. So far as I understand, it is an implementation of a vector space model with the cosinus similarity. This model is modified to allow the boost of certain terms. Is this right or did miss something? Cord

Using Reader to index Stored value.

Hi All, Why can't we use Reader to index stored value in Lucene. I found it strange. And also in the code I saw that the String value is converted to a StringReader anyway. Any reason why? Regards, -- Victor Hadianto NUIX Pty Ltd Level 8, 143 York Street, Sydney 2000 Phone: (02) 9283

better search results from 1.2 than 1.3

Hi, I just upgrade Lucene 1.2 to 1.3 on the same index built original from Lucene 1.2 and then latter from Lucene 1.3. I also changed the default operator to AND. It seems work fine but actually the search results from Lucene 1.3 are not as good as the results from 1.2 (same index and same

You didn't provide details about your setup, but my first guess is that all your processes are writing the indices on the same disk, and that disk is your bottleneck. Otis --- Killeen, Tom [EMAIL PROTECTED] wrote: I am attempting to create approx 10 different Lucene indexes. I'm trying to

query parser operator precedence and strange result

Hi, im currently trying to understand how the standard query parser handles operator precedence in a query like a OR b AND c OR d This is output by the toString method as a +b +c d so AND seems to have higher precedence than OR Now if I try to check this and look at a OR ( b AND c ) OR d I see a

Lucene as a high-performance RDF database.

I have been giving some thought to using Lucene as an RDF database. I'm specifically thinking about the RDF model and not the RDF syntax. Essentially this would just comprise triples encoded in a document as fields. So for example we would have subject predicate and object relationships as

You should re-index using 1.3 when you upgrade the library to 1.3. I don't know the differences specifically (without doing some CVS diffs) but there were some changes that affect the index format. Erik On Tuesday, August 5, 2003, at 11:48 AM, hui wrote: Thank you, Sebastien. It works now.

Re: Checkpointable Index

As long as you finish any index operations when you checkpoint it, there should be any problems. A Lucene index is just regular ol' filesystem files just like everything else, so there is no problem storing it off and using it later. Erik On Thursday, August 7, 2003, at 12:56 PM, Rob Outar
