// QueryForecast API operation for Amazon Forecast Query Service.
//
// Retrieves a forecast for a single item, filtered by the supplied criteria.
//
// The criteria is a key-value pair. The key is either item_id (or the equivalent
// non-timestamp, non-target field) from the TARGET_TIME_SERIES dataset, or
// one of the forecast dimensions specified as part of the FeaturizationConfig
// object.
//
// By default, QueryForecast returns the complete date range for the filtered
// forecast. You can request a specific date range.
//
// To get the full forecast, use the CreateForecastExportJob (https://docs.aws.amazon.com/en_us/forecast/latest/dg/API_CreateForecastExportJob.html)
// operation.
//
// The forecasts generated by Amazon Forecast are in the same timezone as the
// dataset that was used to create the predictor.
//
// Returns awserr.Error for service API and SDK errors. Use runtime type assertions
// with awserr.Error's Code and Message methods to get detailed information about
// the error.
//
// See the AWS API reference guide for Amazon Forecast Query Service's
// API operation QueryForecast for usage and error information.
