Like firefox you can add any custom search in Google Chrome. Here I will teach you how to add any custom search to Google Chrome and we will take the example of Wikipedia search and Google translate to understand it more clearly. As you can see in the image above, in my Google Chrome when I add wiki in the omnibox then I am asked to press “tab” and then type the search term. Now hit enter and wikipedia search page opens with the results.
Procedure to add custom search to your Google Chrome
Open the website which already has a search box and which provides the search feature. Copy the URL
Like in wikipedia when you search for something in their search bar then you get this URL
Next to search= are the keywords which you searched in wikipedia. But you need to delete those keywords and all that is of important is the URL shown above.
Right Click in the omnibox (address bar) and click on ‘Edit search engines’. Now click on ‘Add’ button and then you will be asked to fill three text fields.
In the current example of Wikipedia here is what you have to enter:
Keyword: wiki (this is what you type in the omnibox so as to search wikipedia)
URL: http://en.wikipedia.org/wiki/Special:Search?search=%s (you need to append %s next to the URL so that Google Chrome could convert that URL to default search engine)
Similarly, for Google Translator here is what you need to enter:
Name: Google Translate (English)
Now you can repeat the procedure for any website which offers custom search.
