Place an asterisk before the name that you are searching for.

For example:
You are searching for Davis & Johnson Pharmaceuticals, but you can only remember part of the name: Johnson.
Click Quick Find, and enter Johnson in the Last/Org name field. You will get zero results.
Place an asterisk before the name, so it appears: *Johnson to get the results you are looking for.

OR

To allow Quick Find to search by a specific word in the organization name, add a backslash before the name that would be used in the search (no spaces). For example: Estate of Robert\Hernandez. This enables you to search for this record by Hernandez. When printing the name, it prints without the backslash.
