Allow Search Nodes to reference ancestors beyond GRANDPARENT (e.g., GREATGRANDPARENT)

Explain the problem as you see it

Currently, Search Nodes only support referencing up to the GRANDPARENT node. When a Search Node is nested deeper, it becomes impossible to access data from higher-level ancestors (such as GREATGRANDPARENT or beyond). This limitation restricts the flexibility of data modeling and makes it difficult to create reusable templates or structures that rely on information from more distant ancestors.

Why is this a problem for you?

I often need to build complex hierarchies where a deeply nested Search Node must reference fields or values from ancestors more than two levels up. The current limitation forces me to have a flat note hirarchy.

Suggest a solution

Introduce additional ancestor references in Search Nodes, such as GREATGRANDPARENT or a generic way to reference any ancestor by level (e.g., ANCESTOR[3]). This would greatly enhance the flexibility and power of Search Nodes for advanced users.
