In my mind this restriction only apply on a query with just a MUST_NOT clause and not to a composed query. I've wrong.

thanks a lot,

Nicolas

: If  I search with boolQuery, Lucene doesn't find anything.
: If I modify by hand the query from "+(-(FILE:abstract.htm))
: +(PATH:/bssrs)" to "-(FILE:abstract.htm) +(PATH:/bssrs)", Lucene find
: the correct list of document.

: Does somebody know why ?

you can't have a boolean query containing only MUST_NOT clauses (which is
what (-(FILE:abstract.htm)) is.  it matches no documents, so the mandatory
qualification on it causes the query to fail for all docs.
