Elasticsearch - Mappings and Data Types

You want to filter documents where a boolean field is_enabled is true and a binary field file_data exists. Which Elasticsearch query correctly combines these conditions?

A{"bool": {"must": [{"term": {"is_enabled": true}}, {"exists": {"field": "file_data"}}]}}

B{"term": {"is_enabled": true, "file_data": true}}

C{"exists": {"field": "is_enabled"}, "term": {"file_data": true}}

D{"bool": {"should": [{"term": {"is_enabled": false}}, {"exists": {"field": "file_data"}}]}}

Step-by-Step Solution

Solution:

Step 1: Understand boolean query combining conditions
The bool query with must requires both conditions to be true.
Step 2: Check each condition
Term query checks is_enabled true, exists query checks presence of file_data.
Final Answer:
{"bool": {"must": [{"term": {"is_enabled": true}}, {"exists": {"field": "file_data"}}]}} -> Option A
Quick Check:
Use bool must to combine term and exists queries [OK]

Quick Trick: Combine conditions with bool must for AND logic [OK]

Common Mistakes:

MISTAKES

Using should instead of must
Combining term queries incorrectly
Misusing exists on boolean fields
