Search, how to deactivate plugins on search results pages
In the Search Settings section you can decide the plugins you want to keep active when the Search Results Page is shown.
In the example above we keep active only Freesoul Builder and Buddypress on the search results pages.
It’s up to you to understand what plugins you need on the search results page. This will depend on the theme you are using. Usually, this page shows only the posts excerpts.
