If you don't define df (which means "default field"), then every query must indicate which field(s) it will query, or you will see that error message. It sounds like the query that is in the ping handler needs to be changed so it includes a field name. Typically ping handlers use *:* for their query, which is special syntax for all documents, and works even when no fields are defined. That query is usually extremely fast. Thanks, Shawn
