Unclear documentation for min, maxDuration for traces #96
Description
A trace is a collection of multiple spans. What does it mean to pass maxDuration or minDuration to the /api/traces endpoint? The documentation says:
minDuration: Ex. 100000 (for 100ms). Only return traces whose Span.duration is greater than or equal to minDuration microseconds.
maxDuration: Only return traces whose Span.duration is less than or equal to maxDuration microseconds. Only valid with minDuration.
Must all spans in a trace be larger than minDuration, if set? Must only one span in a trace fit within the min and max duration parameters? It's not really obvious what the intention is here.
