How create Query

[Anton Potehin <an...@orbita1.ru>]

I have two fields in the index called "first" and "second". Is it
possible to make search using following condition: the "first" field
must have "car" and the "second" field must have "java" or "sun"? If it
is possible, please tell me how?

Using QueryParser, this expression would give you the query you desire:

     first:car AND second:(java OR sun)

Using the API, you can construct this query using BooleanQuery with  
two required clauses, the first clause being a TermQuery for car on  
the "first" field, and the second clause being a nested BooleanQuery  
with two optional TermQuery's for java and sun on the "second" field.
