Elasticsearch - Search Results and Scoring

You want to return all fields except password and ssn from documents, but also include only the name and email fields explicitly. Which source filtering configuration achieves this correctly?

A"_source": { "includes": ["name", "email"], "excludes": ["password", "ssn"] }

B"_source": { "include": ["name", "email", "password", "ssn"] }

C"_source": { "exclude": ["password", "ssn"] }

D"_source": { "include": ["name", "email"] }

Step-by-Step Solution

Solution:

Step 1: Understand combined includes and excludes
Using both includes and excludes lets you specify fields to return and fields to omit.
Step 2: Analyze options
"_source": { "includes": ["name", "email"], "excludes": ["password", "ssn"] } includes name and email but excludes password and ssn, matching the requirement.
Final Answer:
"_source": { "includes": ["name", "email"], "excludes": ["password", "ssn"] } -> Option A
Quick Check:
includes + excludes together filters fields precisely [OK]

Quick Trick: Combine includes and excludes to fine-tune returned fields [OK]
