Editor Q: Search - multiple variables

The node red flow search function is very helpful. I appreciate the drop down options (like Current Flow). I do however at times desire to enter multiple variables, such as:

flow.set, "switch" ... or ... flow.set && "switch"

Does it have one? If not, could it be considered to add one? There are many reasons for this but as a simple example, some times I've entered

flow.set("switch3.online", true) .. or .. flow.set('switch3.online', true)

I know the Q will be how do we distinguish between a comma used to separate variables and the desire to search for the comma too?

My suggestion would be to add it as an option to the drop down list and the search occur between the start of an instruction and the ";" at the end (for multi-line instructions). It does not need to have other options (like Current Flow).

Just a suggestion.
