Hi, elastic team.

I'm working on percolator index with match\_phrase query and keep\_words\_filter.

I found that match\_phrase query is not working properly with keep\_words\_filter.

I've tried both match\_phrase query and simple\_query\_string with "", but both don't work properly.

Both worked as match query with operator 'or'.

Without keep\_words\_filter, both works properly.

Is there any way to fix it?

Thanks in advance.
