Set Up Common Content Filters
The following table provides instructions for creating common types of content
filters. For each filter, also select the Routing method you want to apply—that is,
the action you want Content Manager to take if the filter captures a message.
To capture messages that
contain this content:
Enter the following:
Specific word or phrase in
the message Subject Match: Any Rule
Select Location: Subject Line
Select Filter Type: matches regex
Value: Enter the word or phrase, in the
following regex syntax:
• For a single word, enter: \Wword\W
• For a phrase, separate words with \s:
\Wword\sword\W
Tip: To capture messages don’t contain any
other text in the Subject line, select equals for
the Filter Type, and enter the word or phrase
without using regex syntax.
