I tried searching for what kind of GraphQL support they offer on their repo (which is an advertised feature) and it still seems to be a WIP, though you have to kind of dig through the readme to find that out. Same problem with the full-text indexing feature, as another user here mentioned.
Hi user1029384756 - Tobie here, founder of SurrealDB. We do plan to support GraphQL integration soon (hopefully before our final 1.0 version). Our features page https://surrealdb.com/features is the best place to see what is built, and what we intend to build in due course! Hope this helps!
