Tous plugins de recherche inactif et ça cherche quand même

Well, it's not a problem to make a search plugin, i had make one before.

My problem is i can't call it from flexi template, and i can't put the result in a flexitemplate.

And i need different result templates for differents flexi categories.

It seems Flexisearch is not used by standard search field and not by filters. With which files work filters and this basic search file on title ?

Thanks
