language filter query is not working for two sources
i am using the below query to filter "en" language results.
args.queryBuilder.advancedExpression.addFieldExpression('@@language', '==', ['en']);
This is working for one data source and not working for another data source. I am using JS framework with coveo cloud.
i run the query without langauge filter and found that the below 2 difference.
], ---> datasource 1
"language": [ "English" ], --> datasource 2
Is there any reason why i am getting the different language code here? Do i need to change the Query here?
