Is there any method for Optimization on the scene.
My search is always like this sex:boy and isbig:yes But I only need the top 4 result ,not need sort by score. The stored in lucene frq doclist file maybe like this Sex,boy -> 1,2,3,4,5,6,8,9,10…..9999999,1000000……100000000,10000001 isbig,yes-> 9999999,1000000,1000001, 1000002……100000000,10000001 so the top 4 result may be is 9999999,1000000,1000001, 1000002. Bit the doclist is so big ,need lots of IO to read all of them,but I only need the top 4 So is there any method can do for this ,not weast so may io First The doclist is ordered Second we can jump some of doclist at head There wen we collect 4 doclist is enough ,not need to read other doclist at end of the 4 doclist The search maybe quickly .
