# What does $UseTextSearchQ do? Mathematica 11.2 features a new built-in symbol in the Global context: Global$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 Nov 27 '17 at 8:41
• I have claimed it here – yode Nov 27 '17 at 9:12

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.
• 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. – m_goldberg Nov 27 '17 at 0:27
• V11.1.1 starts up with a clean Global` context -- kind of makes it stand out among recent releases. – m_goldberg Nov 27 '17 at 8:51
