In current Chrome, right-click the address bar, select "Edit search engines..." and scroll to the bottom of the lower list of search engines. You need to fill in the three boxes for name, keyword and URL. If any of these do not have valid text entered, they will be filled in with a grey background and there is no way to add the search engine.

Click the three-dot icon to "Make Default," "Edit," or remove a search engine from the list. Select the "Add" button to enter a search engine not found on the list. Open the Google Chrome app on your device, then tap the three-dot menu icon in the top-right corner. Select "Settings" from the menu. Choose one of the search engines from the list.

Go to chrome://settings/searchEngines If you have old search engine related google, delete it before the these settings. Find Other search engines and click to Add button

First, visit a search engine (or a website with a search feature). Chrome will automatically detect and add the search engine, if that site supports this feature. Next, right-click in Chrome's location bar and select "Edit Search Engines". Search engines from websites you've visited will appear in the "Other search engines" box.
