I have just added the plugin to my site and it’s working well. What I would like to do is add another index to the search. The reason being I have other pages which are outside of Wordpress which I want to include in the search. I am happy to write to the index directly I simply want the search to return the pages along with the posts and other items. The extra pages will have “permalinks” so hopefully it should be fine.
I would prefer to add the pages to a separate index just to make it easy to refresh them on their own.
I did look at the existing hooks and filters and did not spot anything, but apologies if the function is already there.
