So, just to confirm, using Lucene 4.0, we would be able to issue a search on one or more fields and would be able to get the results sorted by a custom field and also would be able to get the score of each document based on the frequency of the terms searched in all the indexed fields of that document (rather than getting it scored just by the fields in the query, which is the case now).
If this is true, could be please guide me into the direction on how to implement it? Thanks a lot for your help. -Siraj (212) 306-0154 -----Original Message----- From: Simon Willnauer [mailto:simon.willna...@gmail.com] Sent: Tuesday, October 23, 2012 3:51 AM To: java-user@lucene.apache.org Subject: Re: Scoring based on document hey there, in Lucene 4 you can override the termStatistics / CollectionStatistics used for scoring in the IndexSearcher. You can take multiple fields into account here in order use it for scoring. Here is the javadoc link: http://lucene.apache.org/core/4_0_0/core/org/apache/lucene/search/IndexSearcher.html#termStatistics(org.apache.lucene.index.Term, org.apache.lucene.index.TermContext) http://lucene.apache.org/core/4_0_0/core/org/apache/lucene/search/IndexSearcher.html#collectionStatistics(java.lang.String) simon On Mon, Oct 22, 2012 at 11:25 PM, Siraj Haider <si...@jobdiva.com> wrote: > I am using DefaultSimilarity and did not boost any field while indexing.
