// Retrieves IDs and annotations for traces available for a specified time frame
// using an optional filter. To get the full traces, pass the trace IDs to
// BatchGetTraces . A filter expression can target traced requests that hit
// specific service nodes or edges, have errors, or come from a known user. For
// example, the following filter expression targets traces that pass through
// api.example.com : service("api.example.com") This filter expression finds
// traces that have an annotation named account with the value 12345 :
// annotation.account = "12345" For a full list of indexed fields and keywords that
// you can use in filter expressions, see Using Filter Expressions (https://docs.aws.amazon.com/xray/latest/devguide/xray-console-filters.html)
