Search multiple Fields

I'm searching, for example

title:world OR contents:world OR author:world

Is it possible to know where (in which Field) have Lucene found 'world' in each Document,
without making 3 queries ?

Thanks.

Not in a straightforward way, but you can dig through the Explanation 
returned from IndexSearcher.explain() to see what factors are involved 
in the score, which does include info on what fields/terms were 
matched.
