Robert Muir commented on LUCENE-1360: ------------------------------------- Now that we have custom norm encoders, is this one obselete? you can just use SmallFloat.floatToByte52 to enc/dec your norms? > 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-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
