| description | Search / log-retrieval engines in DBClient: Elasticsearch 8.x and OpenSearch. Use this skill when adding, debugging, or modifying such a Tester.

DBClient Engine: Search
Covered Testers and Aliases
| Engine | Tester | Aliases |
|---|
| Elasticsearch 8.x | ElasticSearchTester.java | elasticsearch, elasticsearch8, elastic, es |
| Elasticsearch 7.x / OpenSearch | OpenSearchTester.java | opensearch, elasticsearch7 |
Key Dependencies (build.gradle)
// Elasticsearch 8.x
implementation 'co.elastic.clients:elasticsearch-java:8.8.2'
// OpenSearch / Elasticsearch 7.x
implementation 'org.opensearch.client:opensearch-rest-high-level-client:1.2.4'
implementation 'org.apache.httpcomponents.client5:httpclient5:5.2.1'
Key Concerns
- Elasticsearch 8 and OpenSearch client APIs have diverged, hence two separate Testers.
- Both usually speak REST/HTTP; the query parameter can be DSL JSON or a simplified query string, depending on the Tester.
- Authentication, TLS, and index name handling differ; check the specific Tester implementation.
Minimal Verification Command (Elasticsearch 8 Example)
java -jar build/libs/oneclient-1.0-all.jar \
-h 127.0.0.1 -P 9200 -e elasticsearch -t query \
-q '{ "query": { "match_all": {} } }'
Maintenance Notes
- Do not register
es / elasticsearch to OpenSearchTester.
- When upgrading the client SDK, watch for transport protocol version and Java API breaking changes.
