Mahendra,
Could you provide a concrete, and simple, example of what you're trying
to achieve? It would help me understand what you're after.
Any Query implementation works fine as a clause within a BooleanQuery,
there is nothing special to do for a PhrasePrefixQuery in this regard.

We need to delete a lucene index from our application using

There is no lock on the index directory. Interesting thing is that the

This smells like a Windows issue. It is possible that something in
your JVM is still holding onto the index directory (for example,
FSDirectory), and Winblows is not letting you remove the directory. I
bet this will work if you exit the JVM and run java.io.file.delete()
without calling Lucene.
Yep, It works if I exit the JVM and run file.delete() from a different
class without using Lucene.
