Filter questions with specific tag literally (excluding synonyms)

Question

Is it possible to filter questions on Ask Different (or any Stack Exchange site) with a specific tag literally excluding the synonyms?

E.g. I am trying to list all the questions with tag sed, but the list returned contains all the questions tagged with unix, of which sed is a synonym.

The count of questions tagged with unix is pretty high, and it will be time consuming to sift through them to locate the questions matching the tag sed literally.

Answer 1

It looks like this is not possible because upon synonimizing, all instances of sed get replaced by unix. This includes post history data in SEDE.

The closest you might be able to get is a search for [unix] sed is:q. But I'm not sure how you'd be able to check which questions were originally tagged sed and which not.
