Re: problem with not operator

[Erik Hatcher]

Try using an IndexSearcher.explain on a document in the search results 
that you know has "b" - this will give you the gory details of why.

Also, try to simplify without MultiFieldQueryParser - its got plenty of 
known issues - for now and see what that gives you.

Hi,
When I am putting the query as 'a not b' there are some documents 
coming up
which have 'b' as well.

I am searching on 3 fields using a MultiFieldQueryParser and while 
debugging
the query is also getting shown as
(field1:a -field1:b) (field2:a -field2:b) (field3:a -field3:b)

Yet the results have documents which contain 'b' terms as well.
While indexing, I am using StandardAnaylzer(stopwords), and the field 
as:
Field fl = new Field("indexhd",indexhd, true, true, true);

etc..
Please could you suggest what the problem could be?

Niraj
