Be able to modify collection search history

What steps will reproduce the problem?
1. Search and click on a game you don't own
2. Select that game and find out it is the wrong one.
3. The wrong game now shows up in the drop down short list of titles in future 
searches.

What is the expected output? What do you see instead?
I'd like a way to delete this entry. Maybe you can expose all the search 
results in a list or maybe there can be a way where you long press on an entry 
when you search that pulls up a context menu where you can delete the bad 
result.

What version of the product are you using? On what operating system?
4.3 on android

Please provide any additional information below.
This is less important to me than the ability to search the forums.
