@mingshl,it seems that only the null_value may affect the exist query, if here is not clear, I can temporarily rewind the logic: we should remove the sub key, when the the sub value is null.

Those unit tests add in FlatObjectFieldMapperTests.java and [106_flat_object_with_parameter.yml, including exception cases, if you have any cases, I'd be happy to add them.

@mingshl maybe we should first consider the case of null_value? #14069.

@msfroh I have a little doubt, please help confirm when you are free:

• If we just support object value in flat_object field, do we need to support null_value?

• If we do, null_value must be an object field?
