| Description |
|
There are many optimizations that occur in $_internalUnpackBucket's doOptimizeAt() function. Ensure that, in the case where multiple of these rewrites are possible, the rewrites will combine as expected and occur in a sequence that results in optimal pushdown into the find layer. |
