来自：
1. Click on the wrench/tool icon at the top of Google Chrome and go to Options.
2. On the “Basics” tab, go to the “Search” item and click on “Manage Search Engines”
3. Go to the very bottom of the new page that opens and you will see three empty boxes.
4. For the first box (leftmost), give any nickname for the engine. I gave “EncryptedGoogle”
5. For second box, give a keyword that invokes the new search engine. I gave “encrypted.google.com”
6. For last box, give the url for the search engine. This should be
https://encrypted.google.com/search?{google:RLZ}{google:acceptedSuggestion}{google:originalQueryForSuggestion}sourceid=chrome&ie={inputEncoding}&q=%s
7. Press Enter and the engine will be added to the list. Then hover over the engine row and click on “Make as default”. And you are done.
Happy safe searching
