We are working on a project that uses many custom search features with the Search WP plugin. We are not getting the results we need and reached out to the Search WP support.
We are using the Beaver Builder theme and have developed a custom child theme. Can you tell us if there might be any conflict with the BB theme and using this plugin?
They said this:
Either the active theme or an active plugin is preventing SearchWP from running at all, which is why you’re seeing these extra results. It’s likely that some other code is either running it’s own partial-match search, or having WordPress run it’s own native search (which performs partial matching).
I turned on debugging for SearchWP and you can see on the search results page that SearcWP did not run: http://d.pr/i/12rbn
I would suggest temporarily activating the Twenty Fifteen theme to see if the issue persists, so as to narrow down whether it is an issue with the active theme or another active plugin.
