Is your feature request related to a problem? Please describe:
None Describe the feature you'd like:
We have IndexMergeUnion already, we now want IndexMergeIntersection. So different conditions connected by and can use multiple indexes.
In some situations, performance of IndexMergeIntersection is better than IndexLookUp and Selection + TableScan. For example, when you are sure the intersection of multiple indexes can filter most of data, IndexMergeIntersection is good to use. Describe alternatives you've considered:
