Relevanssi Premium is a search plugin that replaces the default site search in WordPress with something that is more powerful, more extensive and more flexible. Relevanssi Premium can search for taxonomy terms, custom fields, user profiles, and that’s just the start – once you get into code level, you have full control over what goes in the index and what comes out as search results.
Want to find PDF files by searching for their contents? Relevanssi Premium can also read the contents of most attachment file types. Relevanssi Premium can also perform searches that span multiple sites in one multisite installation.
Licenses are either annual or permanent, but whichever you choose, your license is unlimited: you can use Relevanssi Premium on as many sites as you wish. Our customer support generally replies in couple of hours and works hard to solve your problems.
