Limit or no limit using CRM 2011 Quick Find queries

In CRM 2011 Rollup 10 there is a new system setting where you can choose to limit or not to limit the amount of records that is returned by quick find.
The default setting is to limit the records returned when users search using quick find queries.
As a best practice this should also be limited as it might impact performance of CRM if users do these kind of Quick Find queries.
Users should be using advanced find when searching for records that returns more than a few results.
If you choose to disable the limit for quick find queries you will find the setting under Administration / System settings and in the bottom of the general tab you can select “no”
  
The limit is 10,000 records
If a user performs a Quick find that returns more than that an error will be displayed

Error
The Quick Find limit is exceeded. Narrow your search by entering a longer query, or use Advanced Find.
But there might be business requirements to disable this limit and now you can do it from the System settings.
