how to make the closer word have higher weight in sphinx

Question

all

I have a question, I'm using sphinx as search engine.

for example, I have these data:

 aaa bbb ddd cdd
 aaa ddd bbb cdd
 aaa ddd

and now, I'm searching aaa ddd I want the ese ones are all matched, and shows like that order:

  aaa ddd            #total matched. so shows first
  aaa ddd bbb cdd    #there is no word in aaa and ddd, so it can have high weight
  aaa bbb ddd cdd    #as there is word in aaa and ddd, so lower weight

in a word, I want to make the strhing have the keyword I typed closer have higher wight. is there any way to do that? thanks very much

Perhaps, you should change to EXTENDED match mode to enable rankers other than MATCHANY. Looks like SPH_RANK_SPH04 is a good point for a start. Refer to documentation.
