How to Search our Records:

Clicking the Search button, without specifying any search criteria, will return the entire listing.

Use the "^" (caret) character, accessed by hitting SHIFT 6 on your keyboard, to narrow your search to records that begin with a particular string. For example, using ^ACME will only return records that begin with the string "ACME". Simply specifying ACME (without the caret) will return records that contain "ACME" anywhere within the string.
