Step-by-Step Solution
Solution:
Step 1: Identify need for independent querying
Since each address must be queried independently, nested type is required.Step 2: Check mapping details
"addresses": { "type": "nested", "properties": {"street": {"type": "text"}, "city": {"type": "keyword"}, "zip": {"type": "keyword"}}} correctly defines addresses as nested with proper properties. "addresses": { "type": "object", "properties": {"street": {"type": "text"}, "city": {"type": "keyword"}, "zip": {"type": "keyword"}}} uses object type which does not isolate objects. Options A and D are incorrect types.Final Answer:
Use nested type with properties for addresses -> Option BQuick Check:
Nested type needed for independent queries on object arrays [OK]
Quick Trick: Use nested type for arrays of objects needing separate queries [OK]
Common Mistakes:
MISTAKES- Using object type for independent queries
- Defining addresses as text or keyword
- Missing properties inside nested mapping
