I am facing an issue and I may sound silly in asking this but really need to know if any solution to this is available.
The condition being I have two fields title and statement. Title where as is a small field with not more words but statement is a multivalue field and can have any number of symptoms. Now the issue arises when we search for beautiful evening and there is match in both title and statement for exact word and as both field are provided with same boost so the general idea is both will be having same relevance score. But the issue arises because of idf whenever there is a match in title it that doc gets higher relevance than when there is a match in statement field.
I have tried copying both field into third field but that has failed because it also provided same boost to doc in which there is one word in title and another in statement.
The idea which I am looking at if by any possible way we could manipulate the idf calculation , while calculating the idf it should refer to a particular field in which we will copy both field so that the idf will remain same.
Any solution will help a lot.
