"description":"An optional filter against labels for the request.\n\nBy default, searches use prefix matching. To specify exact match, prepend\na plus symbol (`+`) to the search term.\nMultiple terms are ANDed.

Accepted units are nanoseconds\n (`ns`), milliseconds (`ms`), and seconds (`s`). Default is `ms`. For\n example, `latency:24ms` returns traces whose overall latency\n is greater than or equal to 24 milliseconds.\n* `label:LABEL_KEY`: Return all traces containing the specified\n label key (exact match, case-sensitive) regardless of the key:value\n pair's value (including empty values).\n* `LABEL_KEY:VALUE_PREFIX`: Return all traces containing the specified\n label key (exact match, case-sensitive) whose value starts with\n `VALUE_PREFIX`. Both a key and a value must be specified.\n* `+LABEL_KEY:VALUE`: Return all traces containing a key:value pair\n exactly matching the specified text.
