[jira] [Created] (HIVE-12617) Documentation: More information about the 'like' operator

Siddhant Saraf created HIVE-12617:
-------------------------------------

             Summary: Documentation: More information about the 'like' operator
                 Key: HIVE-12617
                 URL: https://issues.apache.org/jira/browse/HIVE-12617
             Project: Hive
          Issue Type: Improvement
          Components: Documentation
            Reporter: Siddhant Saraf
            Priority: Minor


The documentation for built-in relational operator "LIKE" does not clearly define what level of regular expression does it support.

It just says "TRUE if string A matches the SQL simple regular expression B, otherwise FALSE."

I would like a proper definition of "SQL simple regular expression".
I'm also specifically interested in knowing if it support character classes ? etc.

Kindly improve the documentation regarding the "LIKE" operator.
