In Worry-Free Business Security, keywords include the following and are used to filter messages:

Words (guns, bombs, and so on)
Numbers (1,2,3, and so on)
Special characters (&,#,+, and so on)
Short phrases (blue fish, red phone, big house, and so on)
Words or phrases connected by logical operators (apples .AND. oranges)
Words or phrases that use regular expressions (.REG. a.*e matches “ace”, “ate”, and “advance”, but not “all”, “any”, or “antivirus”)

Worry-Free Business Security can import an existing list of keywords from a text (.txt) file. Imported keywords appear in the keyword list.

Operators on Keywords

Operators are commands that combine multiple keywords. Operators can broaden or narrow the results of a criteria. Enclose operators with periods (.). For example:

apples .AND. oranges and apples .NOT. oranges

Note:

The operator has a dot immediately preceding and following. There is a space between the final dot and the keyword.

Table 1. Using Operators
Operator	How it Works	Example
any keyword	The Messaging Security Agent searches content that matches the word	Type the word and add it to the keyword list
OR	The Messaging Security Agent searches for any of the keywords separated by OR For example, apple OR orange. The agent searches for either apple or orange. If content contains either, then there is a match.	Type "`.OR.`" between all the words you want to include For example, "apple .OR. orange"
AND	The Messaging Security Agent searches for all of the keywords separated by AND For example, apple AND orange. The agent searches for both apple and orange. If content does not contain both, then there is no match.	Type "`.AND.`" between all the words you want to include For example, "apple .AND. orange"
NOT	The Messaging Security Agent excludes keywords following NOT from search. For example, .NOT. juice. The agent searches for content that does not contain juice. If the message has “orange soda”, there is a match, but if it contains “orange juice”, there is no match.	Type "`.NOT.`" before a word you want to exclude For example, “.NOT. juice”
WILD	The wildcard symbol replaces a missing part of the word. Any words that are spelled using the remaining part of the wildcard are matched. Note: The Messaging Security Agent does not support using “?” in the wildcard command “.WILD.”.	Type “`.WILD.`” before the parts of the word you want to include For example, if you want to match all words containing “valu”, type “`.WILD.valu`”. The words Valumart, valucash, and valubucks all match.
REG	To specify a regular expression, add a .REG. operator before that pattern (for example, .REG. a.*e). See Regular Expressions.	Type "`.REG.`" before the word pattern you want to detect. For example, “.REG. a.*e” matches: “ace”, “ate”, and “advance”, but not “all”, “any”, nor “antivirus”

Using Keywords Effectively

The Messaging Security Agent offers simple and powerful features to create highly specific filters. Consider the following when creating your Content Filtering rules:

By default, the Messaging Security Agent searches for exact matches of keywords. Use regular expressions to search for partial matches of keywords. See Regular Expressions.
The Messaging Security Agent analyzes multiple keywords on one line, multiple keywords with each word on a separate line, and multiple keywords separated by commas/periods/hyphens/and other punctuation marks differently. See the following table for more information about using keywords on multiple lines.
You can also set the Messaging Security Agent to search for synonyms of the actual keywords.

Table 2. How to Use Keywords
Situation	Example	Match/Non-match
Two words on same line	guns bombs	Matches: “Click here to buy guns bombs and other weapons.” Does not match: “Click here to buy guns and bombs.”
Two words separated by a comma	guns, bombs	Matches: “Click here to buy guns, bombs, and other weapons.” Does not match: “Click here to buy used guns, new bombs, and other weapons.”
Multiple words on multiple lines	guns bombs weapons and ammo	When you choose Any specified keywords Matches: “Guns for sale” Also matches: “Buy guns, bombs, and other weapons” When you choose All specified keywords Matches: “Buy guns bombs weapons and ammo” Does not match: “Buy guns bombs weapons ammunition.” Also does not match: “Buy guns, bombs, weapons, and ammo”
Many keywords on same line	guns bombs weapons ammo	Matches: “Buy guns bombs weapons ammo” Does not match: “Buy ammunition for your guns and weapons and new bombs”
