Hi, I’ve got a Ferret index which I’m using through ActsAsFerret on a database with about 300,000 records. Searches on the index (for example wildcard - “A\*”) seem to be truncated at 512 results. This is a problem as I also pass conditions to ActiveRecord which filter this resultset down, often to zero results when in fact the database contains many records which matched the conditions but just happened to be outside the 512 Ferret return. I thought the solution would be setting max terms to a higher value, with something like - Ferret::Search::MultiTermQuery.default\_max\_terms = 5000, however this seems to have no effect. Is there somewhere this value is overridden or could there be some other setting which is restricting the number of results returned by Ferret? Any help or ideas would be great! Thanks! ---

Yes, most probably it’s the boolean query’s max\_clauses option which defaults to 512. If you’re using the QueryParser, you may pass it :max\_clauses =\> 5000 option to globally raise this for all kinds of queries. There should also be a max\_clauses class method in BooleanQuery.
