We installed version 1.1.5 on Magento 2.2.x and got the issue
Fatal error: Class 'Magento\Elasticsearch\SearchAdapter\Query\Builder\Sort' not found in /home/nybargai/public_html/app/code/Bss/LayerNavigation/Plugin/Elasticsearch/SearchBuilderSort.php on line 30
With the Elastic search issue, since Magento 2.2.x does not have class Elastic search, so our module current version does not work on M2.2.x (Elastic search is on the Magento 2.3.x and above).
However, we have hot-fixed to remove the Elastic search to resolve this issue.
To get the fixed package, could you please feel free to send us an email to email@example.com?
When we receive your request, we will send back to you the fixed package of which removes the Elastic search.
If you need any further support, please feel free to contact us.
We are always willing to support you.
