Without to much backstory: I am trying to configure elasticsearch port inside the database. However, I can simply not find the table which holds the elastic search properties. Can anyone help me out here?
Going trough the backend is not gonna be a solution, it has to go trough database.
You can easily find the Catalog Search settings in the backend.
Stores->Configuration->Catalog->Catalog Search
Under the Catalog Search, you'll see the below settings.
Search Engine
Elasticsearch Server Hostname
Elasticsearch Server Port
and some other parameters too.
But if you wish to update the values from the database you can run the below SQL query in your DB tool or MySQL console.
SELECT * FROM `core_config_data` WHERE path LIKE '%catalog/search/%';
Then update the fields with the appropriate values.
Happy Coding!
