Hi everyone, In our search app we'd perform searches with a DisjunctionMaxQuery with code like
searcher.search(query, hits) Now we'd like to add a custom sub-sort so that when the search returns two documents with the same score they will be ordered by a custom field (this is not a boost for two reasons: first, we already use boosting for other goals, second, we may like to add a third level of boosting in the future) I thought I could just change the former line to something like searcher.search(query, null, hits, new Sort(SortField.SCORE_FIELD, new CustomSortField()) but I had unexpected results, so I dropped our custom SortField, and tried the simple searcher.search(query, null, hits, new Sort(SortField.SCORE_FIELD)) which I though should have the same behaviour of our original code: yet, a large part of our tests failed because it appears that the results are not the same as above. So my question is threefold: 1. is the last query really not functionally equivalent to the first? 2. if not, how would the equivalent be? 3. and how can I perform a sub-sorting of the results by relevance first and my custom score field later? FWIW I am using lucene 2.9.1, java 1.6, OSX 10.6. Thanks in advance for any help. -- blog en: http://www.riffraff.info blog it: http://riffraff.blogsome.com --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
