A distance function doesn't behave like equality (that is, when both dist(x,y) and dist(y,z) are true it doesn't follow that dist(x,z) is also true.)KQL doesn't provide a cross-join flavor.

These records may be found in many different tables, so we need set operators such as union and intersection in SQL to merge them into one table or to find common elements.
