You want to store a user's profile with fields: username (exact match), bio (full-text search), and signup_date (date range queries). Which mapping correctly defines these fields?

A{ "properties": { "username": { "type": "keyword" }, "bio": { "type": "text" }, "signup_date": { "type": "date" } } }

B{ "properties": { "username": { "type": "text" }, "bio": { "type": "keyword" }, "signup_date": { "type": "text" } } }

C{ "properties": { "username": { "type": "integer" }, "bio": { "type": "text" }, "signup_date": { "type": "date" } } }

D{ "properties": { "username": { "type": "keyword" }, "bio": { "type": "keyword" }, "signup_date": { "type": "integer" } } }

Step-by-Step Solution

Solution:

Step 1: Match each field to its correct type
Username needs exact matches, so "keyword" is correct. Bio needs full-text search, so "text" is correct. Signup_date needs date range queries, so "date" is correct.
Step 2: Verify the options
{ "properties": { "username": { "type": "keyword" }, "bio": { "type": "text" }, "signup_date": { "type": "date" } } } matches all these requirements correctly. Others mix types incorrectly.
Final Answer:
{ "properties": { "username": { "type": "keyword" }, "bio": { "type": "text" }, "signup_date": { "type": "date" } } } -> Option A
