=== Fuzzy Like This Field Query

The `fuzzy_like_this_field` query is the same as the `fuzzy_like_this`
query, except that it runs against a single field. It provides nicer
query DSL over the generic `fuzzy_like_this` query, and support typed
fields query (automatically wraps typed fields with type filter to match
only on the specific type).

        }
    }
