[BUG] RangeRelation class removed #1833
Description
What is the bug?
The RangeRelation class was removed in https://github.com/opensearch-project/opensearch-java/pull/1697/changes#diff-3f9a4d6d34b3ee2b1cb2d00990c85c5c4d6b47564874ddcd76764c8d8aaad5cb
Why? I don't see any reason since the relation property still exists in RangeQuery but now just expects a string instead of the enum.
How can one reproduce the bug?
Use opensearch-java 3.3.0 or higher
What is the expected behavior?
The RangeRelation class exists and can be used to build RangeQuery queries..
What is your host/environment?
