Can’t make this work with jetsmartfilters by Crocoblock

As I understand WP Extended Search extends the default wordpress search. I’m using Jetsmartfilters by Crocoblock and I’m using the Search Filter. There I can set the filter to use the default wordpress search.

With this setting I’m supposing It will use the default WP search, but extended by WP extended search.

I’m using the jetsmartfilter to filter the jetengine listing grid, but the results are not what I expect: some articles aren’t showing up while I use a specific word that’s in the content of the post.

Does this need further modification to make this combination work?
