What is all that stuff under "manage search engine" in Google chrome?

[Bobby]

I looked in there and found lots of stuff iI.

It says

Search

Set which search engine is used when searching from the omnibox.

Underneath are two menus

One with search engines and the other one says Manage search engines.

It is crammed with stuff. Even Walmart is in it. Lol.

What should I keep in there?n there. Chrome is really slow for me. Do I need this?
