The CrowdHandler pattern matching engine uses POSIX-Extended regular expression syntax.


For example:

.od matches any three-character string ending with "od", including "hod", "mod", and "nod".
[hm]od matches "hod" and "mod".
[^m]od matches all strings matched by .od except "mod".
^[hm]od matches "hod" and "mod", but only at the beginning of the string or line.
[hm]od$ matches "hod" and "mod", but only at the end of the string or line.
\[.\] matches any single character surrounded by "[" and "]" since the brackets are escaped, for example: "[a]" and "[b]".
