Rewrite match quoted phrase queries
Rewrite match quoted phrase queries

The `minimum_should_match_default_analyzer` method is only used in one
place, in constructing queries for quoted searches, and can be
simplified.

- The `type` field has been removed.  As this parameter is always
  `:phrase`, use `match_phrase` rather than `match`+`type`.

- The `operator` and `minimum_should_match` fields aren't used with
  `match_phrase` queries, so they can go away.
