I would like to have an array of strings in an Elastic Search index. Suppose the array is a list of my recent restaurant choices. Each time I go to a new restaurant I add this to my list. I also would like to be able to find all of the users who have a particular restaurant in their list. How can I create the index to handle this kind of mapping? How can I update a list of restaurants? How can I query each users' list of restaurants?

I am using ELK v 6.3.0.

Thanks, Matt
