For example, the regex Friday matches the string Friday. So regexsearch will search for anything in the input string that matches the regex. A regex is constructed by combining many smaller sub-expressions or atoms. The target sequence is either s or the character sequence between first and last, depending on the version used. A pattern consists of one or more character literals, operators, or constructs. Returns whether some sub-sequence in the target sequence (the subject) matches the regular expression rgx (the pattern).
