CI: include newer OpenSearch versions in test matrix
Author: rursprungCreated Feb 18, 2026Updated Mar 12, 2026
Problem description
the CI currently only tests against OpenSearch 2.0.1: https://github.com/infinilabs/analysis-ik/blob/9b820257e288fac34f0d53a7e4439bd21e13600e/.github/workflows/test.yml#L48
Preferred solution
it should also test against OpenSearch 3.x and maybe a newer 2.x minor version.
Alternatives
manual tests before releases.
Additional Information (optional)
for Elasticsearch it tests several minor versions of 9.x: https://github.com/infinilabs/analysis-ik/blob/9b820257e288fac34f0d53a7e4439bd21e13600e/.github/workflows/test.yml#L18
