Is there a Scripto API to search the transcriptions?

The default Omeka API only allows you to search item title and description, but not the Scripto transcription text. Is there a way to do that?

When I search for text from the transcriptions in the Omeka Admin search bar, it does search the transcriptions too, so I know there’s got to be some way to do it, but I can’t figure it out.

I’ve been using the MediaWIki search API and that’s ok, but I have to fetch the MW search results and then decode the base64 page name, then go and fetch the Omeka data from there, and I’d like to streamline that, if possible.
