Hello everyone.  
The term splited from query string are the same to each other in my querying.  
i just want to know how many term matched to a document.  
i dont need es score. i will caculate the score myself with the count of matched term in script score.

for example: the word "iphone 5s" will splited into two words: "iphone" "5s"  
in my scoring script, i may know the number of matched term are 2, 1 or 0.  
then i will caculate the score like: N \* 30 + other\_score;

can this be possible?

i dont know how to get the number of matched term to one doc.  
i now just think of constant\_score that would implement this.
