Bug Description

Despite the resolution of bug #828582, I still experience significant delays in the Dash before my first keystroke appears as well as while the keystrokes appear. Basically, I bring up the Dash, type my search string, then sit back and wait for the characters to appear on screen. Even though I've typed the entire string, the auto search is occuring before the first keystroke and between some (or sometimes all) keystrokes. The delays tend to be on the order of seconds.

I have old hardware, which probably exacerbates the situation.

One option would be to have the Dash frequently check for keyboard input and immediately interrupt and cancel whatever it's doing when a keystroke is detected. Alternatively, perhaps some way to either (1) disable the auto search completely until I press the enter key, or (2) have the ability to set a user-defined delay parameter that holds off on the auto search until after that much time has passed with no keyboard input in the search field.

Note that I originally wrote this as a comment for bug #828582, but was instructed to open it as a new bug.
