Synopsis — The one-line summary of the errata, such as:

Important: OpenSSL Security Update

Erratum Advisory — The way Red Hat Security Response Team codifies Advisories, such as:

 RHBA-2007:0530

Searches can be by done year (such as 2007), by type of Advisory (RHBA for Bug fixes, RHEA for Enhancements, and RHSA for Security advisories), or full Advisory name, such as the example above.

Package Name — For users concerned with particular packages, searching by package name (such as kernel or httpd) is beneficial because search results will be grouped by advisory. For example, searching for kernel-related bugs return result where the all packages with the term "kernel" appear grouped by the advisory for which the bug is related.
