------------------------------------

             Summary: Add document for special char in JSON_VALUE
                 Key: FLINK-24271
                 URL: https://issues.apache.org/jira/browse/FLINK-24271
             Project: Flink
          Issue Type: Improvement
          Components: Documentation
            Reporter: Jingsong Lee


If user has a json string:
{"fields": {"system.process": [0.998]}}
It is hard to write a valid json path to get 0.998.
The correct json path should be '$.fields.[''system.process''][0]'
