Where the fact we are looking for has been defined as a regular expression and will match text.

A wildcard fact is a fact that extracts text from the content using a regular expression or wildcards. In a sense, it defines its own entity zone.

It tends to be defined in situ, and, again, unless the reuse context is extracting the same-named fact with similar semantics, you should only use these once – one per context.

Wildcards (mixed in with actual text) that can be used include:

• * – 0 to any number of characters
• ? – a single character
• ~ – single numeric
• # – 0 to any numeric characters
• ^ – a single uppercase character
