POZITRON: "Unfortunately, it's not built into Chrome's settings; you have to find a file that Chrome saves to your AppData folder. The file path is:
User/YourUserName/AppData/Local/Google/Chrome/User Data
Inside there is a file called 'Local State'. If you open that in a text editor, and search for google.xx, where xx is the domain that Chrome is auto searching, then replace it with the domain you want it to search, things work as expected!
Note that you should close Chrome before editing and saving the file, otherwise it will overwrite your changes when it shuts down.
Hope this answer will be easier to find for other people in this situation!"
