 Description   

There were a few query planner unit tests in our test plan that we missed:

  • Demonstrating that a wildcard index scan can participate in a SORT_MERGE plan.
  • We can use a wildcard index for COUNT_SCAN.
  • Contained $or planning: wildcard index can be used in a plan that tightens bounds through the OrPushdown optimization.
