As a concrete example I am guessing
- a user called themselves msft_2000
- Now every time someone says “What @msft_2000 says” or “what msft_2000 says” this shows up in search
I am honestly not sure what the right thing is to do, I would probably approach this in the reverse direction.
- Some special plugin that turns MSFT → “magical msft onebox with extra data”
- Parse search queries for known stock tickers and do a transform on the search query.
It is certainly going to be very complicated and costly. Only simple workaround I can think of is renaming users.
