   > I think you don't need to file jira for this kind of minor doc fixes. Btw, any other systems supporting `REGEXP` for regular expressions other than Hive? I think we might be able to assign an alias name to it if it is a general name.
   
   So far as i know ,mysql and hive support this key word .But i think a alias name seems a good idea.
   examples:
   `SELECT 'abc' REGEXP '([a-z]+)';`
   Ressult:
   `1`
