Not a known field error

[Jeet Singh]

Hi,

I created a webpages index using Nutch-0.9, while indexing I added a 
field named *s3-type* in each document.
At the time of searching, I'm able to see the same field name and 
related value in each hit retreived but the issue
is that when I try to call addRequiredField to the query, it throws 
error (at runtime) that field s3-type is not a known field.

Here is the code for adding the field at indexing time (in a plugin 
extended from IndexingFilter):-
    doc.add(new Field("s3-type", "some value", Field.Store.YES, 
Field.Index.TOKENIZED));

This is the code during searching (when I try to add a field as required 
field to query):-
    Query newQuery = Query.parse("dummy query", <conf object here>);
    newQuery.addRequiredTerm("value", "s3-type");
    Hits hits = <index searcher obj here>.search(newQuery, 300, null, 
null, false);

I'm able to search properly for all normal queries, the problem comes 
only when I try to do addRequiredTerm

Basically I need to filter the results based on a particular field 
(s3-type in this case).

Please help
Thanks
