Hi, I am looking for an easy (~preferred) way of implementing customized search with Lucene. What I mean by this is changing order of returned hits according to user profile. In simple words I would like to be able to tweak order of documents in Hits collection before it is presented to the client.
Example: if user A issues a query "lucene" then he/she tends to click the third returned link (document #123). I would like to "boost" document #123 for this user so the next time he/she issues the query "lucene" again the hit for the document #123 will be in the first or second position (providing that the index hasn't been modified). Looking at the Searchable<http://lucene.zones.apache.org:8080/hudson/job/Lucene-Nightly/javadoc/org/apache/lucene/search/Searchable.html>interface it does not seem it supports this kind of flexibility. I don't want to use filter<http://lucene.zones.apache.org:8080/hudson/job/Lucene-Nightly/javadoc/org/apache/lucene/search/Filter.html>of sort<http://lucene.zones.apache.org:8080/hudson/job/Lucene-Nightly/javadoc/org/apache/lucene/search/Sort.html>(they are not appropriate for my goal). Custom scoring<http://lucene.zones.apache.org:8080/hudson/job/Lucene-Nightly/javadoc/org/apache/lucene/search/package-summary.html#scoring>seems to be the only option left. At the first glance it seems quite complex; moreover, I am not sure it really allows me to achieve my goal, but if there is no other way then I have to try it... Any suggestions?
