Dynamics CRM Rollup 10 introduced a new feature called ‘Quick Find Optimization’, by default this is set to ‘Yes’ once you apply RU10. Everything works beautifully until a user enters broad search criteria, eg: *xyz. If the system has too many records it’ll simply crash.
If you have a look inside event viewer on the CRM front-end server you’ll see a warning similar to this one.
Exception information:
Exception type: CrmException
Exception message: QuickFindQueryRecordLimit exceeded. Cannot perform this operation.

Only way to get around this is to turn off the Quick Find Optimization through system settings.
Or train the users to search by more specific keywords.
