Query relaxation avoids having several round trips and possibly could be offered with and without deduplication. Maybe this is a feature required for Solr rather than for Lucene. Question: Even if lucene's score is not absolute does it somewhat determine an partial order among results of different queries? J.D. 2007/4/9, Otis Gospodnetic : > Not that I know of. One typically puts that in application logic and re-runs or offers to run alternative queries. No de-duping there, unless you do it in your app. I think one problem with the described approach and Lucene would be that Lucene's scores are not "absolute". > > Otis > . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . > Simpy -- http://www.simpy.com/ - Tag - Search - Share > > ----- Original Message ---- > From: J.
