Please, can someone clarify for me Magento 2.2.9 Community Edition Which Elasticsearch Version can be used with it?
I have Amasty Elasticsearch extension installed - Tests are successful with both Elasticsearch version 5 and 6
I have tried 6.0 but it crashing the whole server at reindexing.
Version 5.0 works but is very very slow.
On the devdocs it's confusing
Magento 2.3.1 adds support for Elasticsearch 6.x, and it is enabled by default. Magento still provides modules for Elasticsearch 2.x and 5.x, but these must be enabled in order to use these versions. Elasticsearch 2.x is still available but strongly discouraged. Versions 2.x and 5.x are End of Life. If you must run Elasticsearch 2.x or 5.x with Magento 2.3.1, you must downgrade the Elasticsearch client to an older version. Follow the instructions in Change the Elasticsearch Client.
Then also mentions
Magento 2.2.8 adds support for Elasticsearch (ES) 6.x. Magento still provides connectivity for ES 2.x and 5.x, but you must manually enable this support.
Am I getting confused between community edition and other Magento versions? Can someone please let me know or provide the URL link for elasticseach on community edition version 2.2.9
