What does $UseTextSearchQ do?

Question

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>>;

As Szabolcs says in his answer, it's a bug, and I have tagged it as such. — m_goldberg, Commented Nov 27, 2017 at 8:41

It's a bug. There should be no symbols in Global` at startup.

PrintDefinitions saying that it has a definition is also a bug. In this version it claims that every single symbol has a builtin subvalue.

$\begingroup$ Yeah, but every release seems to come with some symbols defined in the Global context at start-up. Different ones in each new release. Perhaps WRI pre-release testing should add a test for this. $\endgroup$

$\begingroup$ @m_goldberg I've reported bugs like this multiple times ... it's strange they haven't added an automated test for it yet. $\endgroup$

$\begingroup$ V11.1.1 starts up with a clean Global context -- kind of makes it stand out among recent releases. $\endgroup$
