Do you mean Lucene 2.2? Your stack trace seems to line up with 2.2,
and 2.3 isn't quite released yet.

You may want to look at the FunctionQuery capability, either in
Lucene, or the expanded capabilities (recently added) in Solr.

Hi,
Is there any way to find out if an instance of Query has any terms
within it? I have a custom parser (QueryParser does not do everything I
need) and it somtimes creates empty BooleanQuerys. (This happens as a

What makes you think the query needs to be rewritten to extract terms?
Not the case...unless you want to extract Terms from say, a Wildcard or
Fuzzy query. In that case you need an IndexReader however, as the terms
in the Wildcard/Fuzzy query are determined by what is in your index...

Thanks for the response Michael.
Sorry, I'm using Lucene 2.2. We are using Lucene to index our database

Hi,
We have an application in which we want to index feeds. Each feed is a
collection of articles and some other metadata. The problem is that
sometimes we want to search for feeds and sometimes for articles. As far as
I know lucene doesn't provide any abstraction for grouping its documents.
