I have created a custom search engine to integrate with third party services to get the data instead of Elasticsearch.
After creating the custom search engine I am getting issue with indexers during running indexer command:
Catalog Search index process error during indexation process:
There is no such engine: cognitivesearch
The search engine in core_config_data table is already set as cognitivesearch.
Not getting the exact issue. If anyone faced the same issue please do let me know.
