I've checked the bundle documentation available here => https://doc.oroinc.com/backend/bundles/platform/ElasticSearchBundle/#bundle-docs-platform-elastic-search-bundle
But I was not able to found the bundle code anywhere in vendor and git repo's. Is it removed or available anywhere?
Elastic Search is supported only in the Enterprise Edition of OroCommerce & OroCRM.
For more details, see the documentation: Community vs Enterprise Edition.
