I have few fields indexed as title, bookname, description, author, topic and others and also there is one field "TiBoDe" which contains all values from title, bookname, description.
Now if I do like TiBoDe:game it will not give relevant results So I want to achieve that if someone does like TiBoDe:game I want to boost Ti more than BoDe So I can get more relevant docs returned
Note: TiBoDe is one single fieldname which contains the value of three fields
