Google has removed Search Option from right-click menu in Chrome. ‘Search Google for’ (if you’ve set Google as default search engine) appears on the context menu of highlighted text, you can find this change in latest canary and dev. builds. We don’t know whether Chromium team has done this intentionally or it could be a bug? If you’re using developer or Canary as default browser, you can add it by installing Context Menu Search extension from the Chrome Web Store. 

no search Google for command on right click menu

After installing this extension, visit its options page and select ‘Google’ under Web Search and click on ‘Add selected options’ at the bottom. After that, Context Menu Search lets you search for text you want to find in from any one of the search engines like Bing, Bing Images, IMDB, Wikipedia, Yahoo and Google.
