    # To avoid the inlined resolved records being unreasonably large, you can
    # also specify a custom resolver to be used when rendering the record.
    # For example, the query:
    #
    #      &resolve[]=resource:id@compact_resource
    #
    # will use the "compact_resource" resolver to render the inlined resource
    # records.  This is defined by `search_resolver_compact_resource.rb`.  You
    # can define as many of these classes as needed, and they'll be available
    # via the API in this same way.
