Your product calls it a workspace. Your onboarding emails call it a team space. Two of your help articles call it an account, because they were written before the rename and nobody went back.
Everyone internally knows these are the same thing. Nobody has ever been confused by it in a meeting.
A customer types "how do I leave a team space" and gets nothing useful, because the article that answers it is called "Leaving a workspace".
Synonyms are a solved problem, except yours
Modern retrieval is genuinely good at synonyms. It knows "delete" and "remove" are close. It knows "invoice" and "bill" are close. It learned that from an enormous amount of ordinary English.
It did not learn your rename. Nothing outside your company knows that your workspace and your team space are the same object, because that fact exists in exactly one place: your team's shared understanding, which was never written down.
So the match fails, and it fails silently. Nobody gets an error. The customer just doesn't find the thing.
It gets worse when it half-works
The failure everyone worries about is "no results". The expensive one is a partial match: the system finds an article about accounts, decides it's close enough, and answers a question about workspaces using information about billing accounts.
Your customer gets a confident answer built from the wrong object. You find out weeks later, if at all.
The fix is a list, not a project
You don't need to rename anything. You need one page that says, in plain sentences, what each thing is called and what it means — and you need the old names on it.
"A workspace, previously called a team space, is…" That one clause does the work. It gives both the retrieval system and a human reader the bridge between the word they used and the word you use.
A published glossary is quietly one of the most retrievable pages a documentation site can have, because it's full of short, self-contained definitions. That's exactly the shape retrieval likes.
Then stop the drift
Names drift because there's no agreed source. Write the list, put it where the product team can see it, and add new names to it when things get renamed rather than after.
You do not need to rename anything to start. You need one page that says what each thing is called, including what it used to be called, and the discipline to add to it when something gets renamed rather than after.
