Is it possible to use SpotlightSearch to search for multiple entity types in one service call?

I need to get a list of all the DataTables, Streams, ValueStreams, Blogs and Wikis that belong to a project. It seems the only service that can facilitate this is SpotlightSearch, which works perfect with the field thingShapes set as {items: ["DataTable"]}, but when trying to add another item in that array it returns nothing (meaning when we add {items: ["DataTable","Stream"]}), with no error.

So, is there a way to get all the entities of those types in a single call? It seems to be a bug, from what I looked at, but maybe I'm doing something wrong?

For reference, the other parameters I used in the calls were:

-searchExpression: *

-types: {items:["Thing"]}
