The problems seem to happen mostly with some blocks in the pages, they're not having the text within them be found when that text gets searched.

This isnt happening on every block, only some.

Here is our searchController code:

Hi QRiley327,

Are all your blocks actually indexed? Have you read the documentation about indexing blocks in contentarea: https://world.episerver.com/documentation/developer-guides/search-navigation/Integration/cms-integration/Indexing-content-in-a-content-area/

So have you checked what kind of implementation you have for your blocks in the solution? Perhaps you just have not enabled indexing for some blocks (also possible to switch on and off per instance if you have that property on the block type which an editor then can toggle on and off).
