ElasticSearch Quality Control & Assurance 2

Question 1

Which Elasticsearch API lets you simulate how a document would be analyzed without indexing it?

Accepted Answer

_analyze

Answer

The _analyze API applies a specified analyzer (or field's analyzer) to text and returns the resulting tokens, allowing you to verify analysis behavior without indexing.

Question 2

What does the `_validate/query` API return when passed `explain=true`?

Accepted Answer

A human-readable explanation of why the query is valid or invalid

Answer

With `explain=true`, `_validate/query` returns a textual description of the parsed query structure and any validation errors, without executing the search.

Question 3

Which shard allocation setting should you verify to ensure primary and replica shards are never on the same node?

Accepted Answer

cluster.routing.allocation.same_shard.host

Answer

`cluster.routing.allocation.same_shard.host` prevents allocating primary and replica of the same shard to nodes sharing the same host, protecting data redundancy.

Question 4

How do you confirm that an index template was applied correctly to a newly created index?

Accepted Answer

GET //_settings and GET //_mapping

Answer

Checking `_settings` and `_mapping` on the new index shows whether the template's settings (shards, replicas, analyzers) and mappings were applied as expected.

Question 5

What Elasticsearch feature can automatically enforce that documents in an index match a required structure?

Accepted Answer

Strict mapping with `dynamic: strict`

Answer

Setting `dynamic: strict` causes Elasticsearch to reject any document containing a field not already defined in the mapping, enforcing schema compliance.
