Extend search also to termmeta

I’ve been using your plugin for several months and at least 2 different projects and it’s really useful and it helps me a lot in my work.

I’ve had the need to extend your plugin with new features that I humbly think may be useful to everybody. These allow to search also in the term’s meta.

I think that I can submit you my work in order to let you see what I did and it could be the base for a frontend based research.
I would like to understand whether my efforts can be utilized for future releases of your plugin.
