Hierarchical data in an elastic mapping

Hierarchical data in an
elastic mapping

In an
elastic mapping
, you can use hierarchical fields that represent an array, map, or struct.
You can use hierarchical fields as pass-through fields. You can also use hierarchical fields in an advanced filter condition or use a hierarchical field with a complex operator to access primitive child fields in the filter condition. For more information about complex operators, see
Function Reference
Consider the following guidelines when you use hierarchical fields in a filter condition:
  • You cannot use a hierarchical field in a simple filter condition.
  • Do not use a parameter for the filter condition.
