lucene中的首选字段搜索

Question

I have an index and I want to search it on multiple fields. I am working on Query Builder for this application wherein I want to give more preference to a certain field than others.

Let's say the fields are: RollNo, Name, Age

In this case, when someone searches with RollNo field along with Name , I want to give preference to results which come from RollNo matching.

Anybody knows how to do this in Lucene. I am using Lucene 3.6.

You can use the Query.setBoost() method to boost during query time.
