Because their products are a complete fucking MESS.
Quotes used to be an exact search, but it now overrides that basically everywhere and continues to search for what it thinks you mean (and has for like a decade now). Even though the "Missing: ___ | Must include: ___" popup just wraps that word in quotes in the search. Which is infuriating, since they know damn well adding quotes won't actually search for that word.
In reality, you need to click "tools" -> "all results" and change it to "verbatim" which does at least still appear to work... for now.
