Description copied from interface: FilterParser

Parses the into a filter from the current parser location. Will be at "START_OBJECT" location, and should end when the token is at the matching "END_OBJECT".

The parser should return null value when it should be ignored, regardless under which context it is. For example, an and filter with "and []" (no clauses), should be ignored regardless if it exists within a must clause or a must_not bool clause (that is why returning MATCH_ALL will not be good, since it will not match anything when returned within a must_not clause).
