Are you getting an error when searching for records?
An example would include going to Workplace > Contacts, entering "g" or "ge" in the search field, and an error is thrown as displayed in the screenshot below.
The reason why this error is thrown is because both the search criteria is too broad and the approximate limit on the number of returned records in the Quick Find search tool is about 5,000. As a workaround, you can either be more restrictive in your search [i.e. search for "george" rather than "g" or "ge"] or use the Advanced Find Query Tool if you want to be more broad in your search.
