Actually I was going to suggest a fix for '-' within words in the
query parser.

Otis,

I've done something similar to configure my merge factor (but it was
outside my code), and am planning on setting the limit on boolean queries
this way as well. I think it's pretty clean especially if you use

This looks nice.

They'll mess up the index.
Should we try to prevent this by not offering this option, or should we

If so, then this is likely caused by the fact that your Term contains a

Clandes,
I'm not sure what the "body" field is that you're indexing. If it's a
database record, one option may be to store the database primary key for
the record as a field value -- basically a document ID. In that case,
you would do the search and get back matching document ID's. You could

You can use MultiFieldQueryParser, or you can construct a BooleanQuery
with two TermQueries as its two clauses, and combine them with OR.
