One thing I have noticed is that NutchBean (for example used through  
the little webapp) implements default AND semantics, that is if I type

   nutch lucene

I only get pages that have both "nutch" and "lucene" on them.

However if I do the same in Luke (which directly uses Lucene  
functionality) it implements OR semantics, so it
will return pages that have either "nutch" or "lucene" or both on them.

Basicaly, while nutch does use lucene as underlying engine, nutch  
queries are translated into lucene queries in a non-trivial way.

What is the query you are firing ?
It seems most likely that you are firing A& B

little more information would help in better understanding the problem.

Cheers,
Rohan
