How do I perform an expert search (CCL)?

Common Command Language (CCL) is the most powerful method to search within IRIS. You may access the CCL search screen from the Advanced Search page.

Although CCL can be used for simple searches, it is an especially effective way to perform complex searches, as it affords you a great deal of control over your search results. To use CCL, enter your desired index code, an equal sign and a term. You may use connectors (and, or, not) when combining more than one term.

Search names are three to five characters and can be entered in either upper or lower case. The search string can be one or more keywords, and you can use truncation and connectors with most.
