Julian Hyde commented on CALCITE-5169:
--------------------------------------
Can you describe in this case what the problem was, and what was your fix, and
the relationship with other issues with simplifation/sargs/less-than.
Why did you add two RelOptRulesTest tests that are very similar to each other
and not like the original case "x < 1 or x > 1"? Can you add comments to those
tests about the desired result (because the next person probably won't navigate
to the XML file).
> 'xx < 1 OR xx > 1' cannot be simplified to 'xx <> 1'
