Filter on IDs with RediSearch

Question

Is there any way to restrict RediSearch results by a list of document IDs, which would be specified in the request?

e.g. something like FT.SEARCH cars fast @id:{100,200,300} would return only fast cars having ID 100, 200, or 300.

Answer 1

Yes, there's the INKEYS keyword.

> FT.SEARCH cars "fast" INKEYS 3 100 200 300
