I have two question about how indicies affect queries:

1) If I have an index built for a given field FOO, and perform a query with "like" such as "FOO LIKE 'ABC...' " does it benefit from the index? Or is it only queries with equality conditions that benefit from the index (eg: "FOO EQ 'ABC' ")?

2) If I have an index built with Empties=NO and then query with that indexed field ="", how does it handle the query? Does it not use the index at all?

TIA,
Jeff
