Hello,

I need to map the fields existing in my index to a lookup file.
For eg: In index i am having field=value and in a csv i have value=name , so i need to map field=name. How can this be achieved.

So basically whenever I am searching field , i should also get name as result.

You can use the mutate filter to remove unwanted fields.
