Description of problem:

1) Go to Systems list. 
 2) Search on a fact of the system (like 'red hat*')
3) Hit enter key multiple times , before a result set comes back

Actual results:
The same system matching the query shows up multiple times. It also seems to be the case that multiple consecutive requests to "items" seem to be happening. 

Expected results:
Expect to see no duplicates in the result set.

Additional info:

This could be an enter key thing, because the search click button seems to disable as soon as its clicked.
