Suggestion: Let us use "Collections" syntax in searches to search within temporary collections

Collections are awesome. I love them. But often, I find myself needing to create collections for specific searches. Unfortunately, the more collections you have, the slower Logos runs - so I have to keep deleting these collections when I need them no longer.

But, what if when you were specifying what to search in, you could use the same query syntax as you can in Library or Collections. This way you could create instant, one-time only collections.* Like this:

Here's a mockup of what it would look like:

* Even better, Logos could remember your last five "search in" requests, and if one of these was an 'instant collection' it could offer it again to you.
