    Description

      These are the warnings at compilation time:

      warning(200): IdentifiersParser.g:424:5:
Decision can match input such as "KW_UNKNOWN" using multiple alternatives: 1, 10

As a result, alternative(s) 10 were disabled for that input

      This means that multiple parser rules can match certain query text, possibly leading to unexpected errors at parsing time.
