It will, when parse(String query) is called, construct a query like this (assuming the query consists of two terms and you specify the two fields
titleand
body):
(title:term1 body:term1) (title:term2 body:term2)
When setDefaultOperator(AND_OPERATOR) is set, the result will be:
+(title:term1 body:term1) +(title:term2 body:term2)
When you pass a boost (title=>5 body=>10) you can get
+(title:term1^5.0 body:term1^10.0) +(title:term2^5.0 body:term2^10.0)
In other words, all the query's terms must appear, but it doesn't matter in what fields they appear.
