// Amazon CloudSearch, suggestions are based on the contents of a particular text
// field. When you request suggestions, Amazon CloudSearch finds all of the
// documents whose values in the suggester field start with the specified query
// string. The beginning of the field must match the query string to be considered
// a match. For more information about configuring suggesters and retrieving
// suggestions, see Getting Suggestions (http://docs.aws.amazon.com/cloudsearch/latest/developerguide/getting-suggestions.html)

// endpoint. To get the search endpoint for your domain, use the Amazon CloudSearch
// configuration service DescribeDomains action. A domain's endpoints are also
// displayed on the domain dashboard in the Amazon CloudSearch console.
