Elasticsearch - Basics and Architecture

You want to search documents where the tags field contains either "red" or "blue". Which query is correct?

A{ "query": { "term": { "tags": ["red", "blue"] } } }

B{ "query": { "terms": { "tags": ["red", "blue"] } } }

C{ "query": { "match": { "tags": "red blue" } } }

D{ "query": { "bool": { "must": [ { "term": { "tags": "red" } }, { "term": { "tags": "blue" } } ] } } }

Step-by-Step Solution

Solution:

Step 1: Identify query for multiple exact values
The terms query accepts an array of values and matches any document containing any of those values.
Step 2: Compare with other options
term does not accept arrays, match treats text differently, and bool must requires all terms, not either/or.
Final Answer:
terms query with array of values -> Option B
Quick Check:
Use terms for multiple exact values [OK]

Quick Trick: terms query matches any value in array [OK]
