testx

This function does the same as contains(): it checks a text for the occurrence of a certain string. But doing this it uses regular expressions. You, therefore, have much more possibilities to analyze your given texts.
Using regular expressions might need some extra research. We recommend checking regular expressions on https://regex101.com/ (external link). 
Syntax

testx(string, string, string)

Examples
testx(myText, regex) To return "true" if a given text matches a given regular expression.

Result: true (with the regular expression matching any combination of normal characters and whitespaces between square brackets)
​
testx(myText, regex, flags) To return "true" if a given text matches a given regular expression. Flags can be added to the regular expression.
