# TODO:
#   This is not an actual query,
#   but a pointer to a query buffer.
#
#   Maybe use a Util::MultiBuffer

# Support a BufferedRef query mechanism,
# that will be used for identical subqueries.
# This is especially important for filtering.
# This Buffered Reference supports multiple
# fingers at different positions in the query.

# The ring buffer query is well suited for this.

# Constructor
