By default, the regular expression engine caches
the 15 most recently used static regular expressions.
If your application uses more than 15 static regular expressions,
some regular expressions must be recompiled. To prevent this recompilation,
you can increase the Regex.CacheSize property.(\[([a-zA-Z0-9 ]+)\])|([*]+)|[])
