If you do a subject search for a term containing stopwords (i.e. "a farewell to arms"), you get no hits. If you exclude the stopwords, the search succeeds. This is due to the way Dismax works -- all Dismax fields should have the same form of stopword handling. In our current configuration, the "era" field is incompatible with all of the other fields. We need to clean up our handling of subject headings to solve this problem -- since the existing configuration is a bit ugly and inconsistent, this is a good excuse for improvement.

The attached patch applies the fix for this problem to the 1.0.1 release. You will need to perform a full reindex after applying this patch. Also, in the unlikely event that you are making use of the era facet field in custom code or in marc_local.properties, you may need to make some additional adjustments to your local changes.
