Mathematica 11.2 features a new built-in symbol in the Global` context:
Global`$UseTextSearchQ
What does it do, and how do I use it?
I tried setting Global`$UseTextSearchQ to different values, but I didn't understand how it works.
It apparently has some underlying code according to PrintDefinitions:
<< GeneralUtilities`
PrintDefinitions[Global`$UseTextSearchQ]
Global`$UseTextSearchQ[___][___] := <<kernel function>>;
