Proud Zhang Browser How to replace the search engine

first I understand how to use the search word drag and drop function, with the mouse to select the word to search, drag and drop to the search Toolbar

It's convenient to search by return.

Switch to another search engine, and then click Enter

is the new result coming out?

Point search icon on the dropdown triangle, and select Manage

You can add the search engine you want directly with the Add function

Fill in the name and search string directly (use%us for keywords), OK?
