Relevanssi doesn’t work with everything. Here are some plugin or theme incompatibilities that I am aware of:
Doesn’t work at all
- WP Job Manager (Here’s a fix.)
- NextGen Gallery – NextGen stores all image information in custom tables Relevanssi can’t access.
- FooGallery – Relevanssi can index the images in the galleries, but the galleries themselves are inaccessible to Relevanssi.
