Hello again!

I'm trying to make the search work with the Work posts that contain texts, but can't make it.. I have tried Search Everything, Better Search and Relevanssi plugins that have an option to include custom posts in the index, but still I get no results. There will be a result if a text is located in a standard post field, but if a text is added via Composition(Media) section, then there are no results. Do you know if it's possible to make it work?

Thanks!
Igor
