: If I want to search let's say "ipod" in three different fields (device, : sound,technology) : Would be the same to use a DisjunctionMaxQuery with the tie braker = 1 than : to use a MultiFieldQueryParser with and OR to build the boolean queries?
strictly speaking even with tie breaker of 1, a DisjuctionMaxQuery differs from a BooleanQuery in the details of how the score is calculated when a document matches *some* of the subclasses, but not all .. there is no "coord" concept in DisjunctionMaxQuery. If you look at the explain output of various queries agaisnt various docs you'll see what i mean. -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
