=item B<percentiles>

Computes percentiles for the enclosing bucket. The positional parameter is
interpretted at the percents computed.  If ommitted, the percentiles computed
will be: 25, 50, 75, 90.

=item B<with-missing>

For terms aggregations, adds a C<MISSING> bucket.

=item B<bg-filter>

Only used if the C<--top> aggregation is C<significant_terms>.  Sets the
background filter for the C<significant_terms> aggregation.
