Issue Summary

If the referenced object attributes with the same name (e.g "referencedAttr") exist in many object types/child object types. Searching "referencedAttr = xx" could return 500 errors due to the query is executed in large number of object types.

Steps to Reproduce

1. Create a parent object type and enable inheritance on the parent.
2. Create a reference object type attribute on parent (e.g "referencedAttr")
3. Create many child object types (probably more than 100 child)
4. Search "referencedAttr = xx"

Expected Results

Return results and respond with 200

Actual Results

Return 500

Workaround

Instead of searching across the entire parent object type, narrow the search to a smaller subset of object types/ child object types.
