Give more score to documents that contains all query terms


(Nariman Esmaiely Fard) #1

I have a problem with scoring in elasticsearch. When user enter a query that contains 3 terms, sometimes a document that has two words a lot, outscores a document that contains all three words. for example if user enters "elasticsearch query tutorial", I want documents that contains all these words score higher than a document with a lot of "tutorial" and "elasticsearch" terms in it.

PS: I am using minimum should match and shingls in my query. also they made ranking a lot better, they did not solve this problem completely. I need something like query coordination in lucene's practical scoring function. is there anything like that in elastic with BM-25?
