In order to find an intersection of two arrays, I use the following APOC call:
apoc.coll.intersection($detailedCriterionIds, childD.detailedCriterionIds)
Could you please show how to implement the same with pure Cypher without APOC help? Thanks!
You can use list comprehension.
[x IN list1 WHERE x IN list2 | x]
In this example, you iterate over all elements in list1 and only keep those elements that are also in list2
