# The following tests verify that the fts4aux module uses the full-text
# index to reduce the number of rows scanned in the following circumstances:
#
# * when there is equality comparison against the term column using the
# BINARY collating sequence.
#
# * when there is a range constraint on the term column using the BINARY
# collating sequence.
#
# And also uses the full-text index to optimize ORDER BY clauses of the
# form "ORDER BY term ASC" or equivalent.
#
# Test organization is:
#
# fts3aux1-2.1.*: equality constraints.
# fts3aux1-2.2.*: range constraints.
# fts3aux1-2.3.*: ORDER BY optimization.
