Pouria,

Here is the function documentation:
https://ci.apache.org/projects/asterixdb/sqlpp/builtins.html

>> If yes, then what is regexp_contains@2 function ?
It checks if the first argument contains a regular expression pattern
defined by the second argument.

>> Can matches@2 and regexp_contains@2 be used interchangeably ?
Yes, they're the same.

Best,
Yingyi
