Some users describe a slow display of results and/or an hanging of FARR when they start searching. Especially with just two characters. To work around it FARR could be extended with an option to start looking for results after a certain amount of characters have been entered.
Example: Start search after 3 entered characters. (Where three can be changed by the user)
"Fi" won't return any result
"Fir" would return "Firefox, Firewall, Firmware, etc)
This reduces the disk access and maybe the load on CPU and memory.
As exception to setting it could be treated as default or set by the user:
- Unless it's an modifier or an alias (so +DC would still return something)
