Perhaps you should try some spelling variations:
"history of the middle ears" » "history of the middle years", "history of the middle ear", "history of the middle earth"
"history of the middle east" » "history of the middle fast", "history of the middle easy"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("history of the middle ears") OR ("history of the middle east"))*.
• Removing quotes may allow a broader search: (( history of the middle ears ) or ( history of the middle east ))*.
