Ivory Search calls itself “a simple to use advanced WordPress search plugin.” This description is an extremely modest, as this versatile plugin ranks as a WordPress All Star in our estimation.
Whatever it is you might want to do regarding search on your website, this plugin is likely to be able to address it. And, if it can’t do something you need in its extremely capable free version, then certainly its premium version should be able to do the job.
Honestly though, we have yet to need to utilize the paid version for any of the sites we have developed for clients.
That being the case, we felt that the least we could do was tout this awesome search addition for any WordPress website that needs search capabilities that go beyond the basic search functionality that WordPress provides.
