Though you've certainly got the syntax to generally AND your searches into the same result, sometimes it's more convenient to use more than one query.
I use a separate utility to append clipboard items together along with a CR/LF between, but I at least would find it very convenient if Everything did this natively from its context menu so that grabbing this and that from all over the place into a single clipboard list was an option. This would enable a certainly level of additional integration into other tools, or even simply a text file with to do items.
Thanks for considering this. Everything is a beautiful tool.
