Match Word or Phrase in a List
Note: You can also use the rule filter “matches any word in” to create a rule that
matches specific words. The rule filter “matches any word” does not, however,
match phrases. Include the words you want to match in the rule value.
Usage example Match any word or phrase in the following list:
• baloney
• darn
• drat
• fooey
• gosh darnit
• heck
Regex example (\W|^)(baloney|darn|drat|fooey|gosh\sdarnit|heck)(\W
|$)
Notes • (...) groups all the words, such that the \W character
class applies to all of the words within the parenthesis.
• \W matches any character that’s not a letter, digit, or
underscore. It prevents the regex from matching
characters before or after the words or phrases in the
list.
• ^ matches the start of a new line. Allows the regex to
match the word if it appears at the beginning of a line,
with no characters before it.
• $ matches the end of a line. Allows the regex to match
the word if it appears at the the end of a line, with no
characters after it
• | indicates an “or,” so the regex matches any one of the
words in the list.
• \s matches a space character. Use this character to
separate words in a phrase.
