More verification should be performed before the actual execution of query in ES by useful information in metadata.

One example is run Nested Loop join on fields of text type which nothing matches from both sides. In this case, we should exit before the execution with useful message to customer rather than confusing empty result.

The new semantic analysis is already merged with many pre-verifications. The Nested Loop example above should be covered elsewhere.
