Elasticsearch - Mappings and Data Types

You want to store a nested object address with fields city and zipcode. How should you define the mapping to ensure Elasticsearch understands the nested structure?

A"address": { "type": "text", "city": "text", "zipcode": "keyword" }

B"address": { "type": "object", "fields": { "city": "text", "zipcode": "keyword" } }

C"address": { "type": "nested", "properties": { "city": { "type": "text" }, "zipcode": { "type": "keyword" } } }

D"address": [ { "city": "text" }, { "zipcode": "keyword" } ]

Step-by-Step Solution

Solution:

Step 1: Understand nested type usage
Nested type allows storing arrays of objects with their own properties.
Step 2: Identify correct syntax for nested mapping
Use "type": "nested" and define "properties" for inner fields.
Final Answer:
"address": { "type": "nested", "properties": { "city": { "type": "text" }, "zipcode": { "type": "keyword" } } } -> Option C
Quick Check:
Nested objects use "type": "nested" with properties = C [OK]

Quick Trick: Use "nested" type with properties for nested objects [OK]

Common Mistakes:

MISTAKES

Using "fields" instead of "properties"
Defining nested fields as arrays or strings
Confusing nested with object type
