Hi Eric, Yes, this is coming from a DB. Unfortunately I have no control over the list of fields. Out of the 1000 fields that there maybe, no document, that gets indexed into Solr will use more then about 50 and since i'm copying the values of those fields to the catch-all field and the catch-all field is my default search field, I don't expect any problem for having 1000 fields in Solr's schema, or should I?
