: Thanks Chris, I didn't know the "solr" package, it is not in the release : distribution, isn't? I'm going to read about it to see if it matchs our : needs.
Solr is a seperate (incubation) project, that builds on top of Lucene, but the FunctionQuery classes have no dependencies outside of the Lucene core. : Our Score = x . LuceneScore + y . SomeField + z . SomeOtherField + w . : YetAnotherField : : Being x, y, z and w our coeffiecients or "scaling factors" in our : ranking function. The thing to watch out for is that Normalizing Lucene scores isn't very "clean" in a mathematical sense, you can asume that a score value of X when searching for "foo" emans the match is as good as a score of X when searching for "bar" http://wiki.apache.org/jakarta-lucene/LuceneFAQ#head-912c1f237bb00259185353182948e5935f0c2f03 The FunctionQuery stuff may make more sense for you, it lets you inject your function right into the lucene score. -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
