Hi-- I just ran into an odd situation. If I do a search including

c* - I get 4 hits
ca* - I get the same 4 documents
co* - I get one new document, not found by c*
Does anyone know what might be going on, or have suggestions for
debugging?
How does your full query look like? Ferret has a built in default limit of 512 for the number of terms wildcard queries (and other MultiTermQueries) can get expanded to. Any more terms matching your criteria will be dropped then, keeping the most relevant 512 terms. You can override this value by specifying a max_terms value when constructing the query via the API:
query = WildcardQuery.new(:field, "c*",
:max_terms => 1024)
you might also try monkey patching the
Ferret::Search::MultiTermQuery::default_max_terms method to return
your custom limit so you dont need to use the query API to construct
your queries (i.e. with aaf which doesn't reliably work with query
objects due to the DRb stuff involved).
It *might* also be a bug in Ferret - if the above doesn't help, can you reproduce this with a simple test case?
