Content Manager 245
Select Filter
Type Select the scanning method that Content Manager uses for
this filter.
• starts with: If text in the specified location begins with
the specified value, this filter captures the message.
• ends with: If text in the specified location ends with
the specified value, this filter captures the message.
• contains text: If text in the specified rule location
contains the specified rule value, this filter captures the
message. This option matches whole words and parts
of words. For example, if you specify the value foot,
and a message contains the word foot, footlocker, or
football in the specified location, this filter captures the
message.
To capture messages with the word foot, without also
capturing messages with the word football, you can
use the matches regex or matches any word in
option.
• does not contain: If text in the specified location does
not contain the specified value, this filter captures the
message.
• equals: If text in the specified location contains only
the specified value, this filter captures the message.
For example, if the value is storewide holiday bargains
and the location is Subject Line, this filter captures the
message only if the subject contains the text storewide
holiday bargains, and no other text.
• is empty: If there is no text in the specified location,
this filter captures the message.
Use, for example, to check for messages that have an
empty sender. See “Create Filters to Allow Valid Null-
Sender Messages” on page 237.
• matches regex: If text in the specified location
matches the regular expression you enter for the rule
value, this filter captures the message. For more
information, see “About Using Regular Expressions”
on page 218.
When you select this filter type, the Test regex link
appears. Click this link to open the Test Regular
Expression panel, where you can make sure your
expression syntax is valid, and catches the type of
content you want. For more information, see “Test
Regular Expression” on page 249.
