Modifier match

Match string against a pattern. The average user may be used to shell patterns or at least in their simplest form to ? and * wildcards so using match instead of ematch for frontend search expression input may be way more convenient for non-programming users.

{$string|match:$pattern}

Special pattern symbols:

• ? — match one or zero unknown characters. ?at matches Cat, cat, Bat or bat but not at.
• * — match any number of unknown characters. Law* matches Law, Laws, or Lawyer.
• [characters] — Match a character as part of a group of characters. [CB]at matches Cat or Bat but not cat, rat or bat.
• \ - Escape character. Law\* will only match Law*
