Say our index has (documents with) three fields "f1", "f2" and "f3" and I want to find all documents matching "foo" and "bar" in any combination of the three fields. 1)The more words that match, the higher its ranking. So it is not really a strict AND-query... 2)The more words that match in a single field, it should be ranked higher. 3)Also, as fields have boost factors, these boosts should ideally be reflected in the ranking too.
What is the most appropriate/elegant lucene-query for this? Possibly a "copyfield" or "catch all field"? I.e. copying/indexing f1, f2 and f3 into an additional field, say "fc", and then looking up in fc only -> "fc:foo AND fc:bar" ? At least (3) is not fullfilled. Thx in advance for advices Clemens PS: I ask because my documents don't have 3, but >20 fields ;), and instead of "foo bar" a user might want to lookup "foo blah whoo bar" ... --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
