Robert Muir updated LUCENE-1360: -------------------------------- Attachment: LUCENE-1360.patch Lance, here's a patch with the similarity i suggested, for lucene's contrib with a unit test. Then, i think as i mentioned earlier (also on LUCENE-2236), we should create a Solr issue to make per-field similarity more declarative and add an example short field type. > A Similarity class which has unique length norms for numTerms <= 10 > ------------------------------------------------------------------- > > Key: LUCENE-1360 > URL: https://issues.apache.org/jira/browse/LUCENE-1360 > Project: Lucene - Java > Issue Type: Improvement > Components: Query/Scoring > Reporter: Sean Timm > Assignee: Otis Gospodnetic > Priority: Trivial > Attachments: LUCENE-1360.patch, LUCENE-1380 visualization.pdf, > ShortFieldNormSimilarity.java > > > A Similarity class which extends DefaultSimilarity and simply overrides > lengthNorm. lengthNorm is implemented as a lookup for numTerms <= 10, else > as {{1/sqrt(numTerms)}}. This is to avoid term counts below 11 from having > the same lengthNorm after stored as a single byte in the index. > This is useful if your search is only on short fields such as titles or > product descriptions. > See mailing list discussion: > http://www.nabble.com/How-to-boost-the-score-higher-in-case-user-query-matches-entire-field-value-than-just-some-words-within-a-field-td19079221.html -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
