I am so happy to finally see a documentation on this topic. I digged over the internet to make searching for custom JPA entity, not generated by ServiceBuilder. thanks, Im gonna try this.

Im having troubles adding FQCN of my class to asset_entries list. first of all I cant find such configuration in my portlet where there is this json based config in liferay 7. but it seems I can only choose between available portlets for search content and mine is not available..
