for my thesis work (Question Answering) I used to retrieve first the document and then play with java to extract the needed answer. for your case what you will do is first locate the positions of the query terms in the document (in this case it might be distributed throughout the document - hence difficult to get the 15/20 words) then count something10 words forward and backward and extract the match. this is the way I handle my problem. Hope there might be different I dea too
