    // filtered or not. This is not possible without either multiple, heavyweight queries
    // or complex multiple indexing, defeating much of the elegance of using elasticsearch for this.
    // So we fudge and order on the first span among the filtered spans - in practice, there should
    // be no significant difference in user experience since span start times are usually very
    // close to each other in human time.
