You can use the braces {} to match two or more regular expressions. For example, in the Preset Manager, {*vector*,*matrix*} will filter for all nodes/compounds that contain “vector” or “matrix”.

That’s a lot of regex typing to filter the ICE presets.

You can also use the braces in the scene search. There seems to be one little gotcha, you’ve got to use some wildcard character otherwise you won’t get a match. For example, {cylinder,null} doesn’t match anything, but {cylinder*,null} or {cylinder,null*} does.
