The content pattern defines which messages the policy is applied to. To understand content patterns, you need to be familiar with the vocabulary.
| Field | Definition |
|---|---|
| Content Pattern | The set of glossary entries applied to the Subject, Body, or Attachments of a message. If more than one glossary entry is applied, the content pattern is composed of all applied entries joined by AND or OR. |
| Glossary Entry | The highest-level vocabulary with which you build content patterns. It is referred to by label (name) in the glossary. |
| Term | A component of a glossary entry. It can be a string expression, a reference to a lexicon of terms, or a reference to an existing glossary term. Terms can be combined using AND or OR, or negated using NOT. |
| Expression | A fragment of text to match to the text of a message. |
| Lexicon | A reference to a file containing a pre-defined collection of string expressions organized into hierarchical categories. |
| Existing Entry | a reference by label/name to a previously defined Glossary entry. Having the ability to use an existing entry as a term allows you to extend a Glossary entry with other terms, creating a new, more specific Glossary entry. |
