# 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.
