 The structured form of the boolean is the same in a request or
    return so that it easy to modify a query. This means some
    fields are only considered in a return value, like counts
    by term. They are ignored in a request.
 The structured boolean supports specific boolean components,
    an unparsed string in query syntax, and UID lists as
    elements of a boolean. This makes it possible to submit
    a single string, a fully structured query, or a mixture.
    The UID list feature means one can also perform refinements
    on UID lists from links, neighbors, or other operations.
    UID list query now returns a history key for subsequent use.
