disabled when using territory-based collations

Key: DERBY-3855
URL: https://issues.apache.org/jira/browse/DERBY-3855
Project: Derby
Issue Type: Improvement
Affects Versions: 10.4.1.3, 10.3.3.0, 10.5.0.0
Reporter: Rick Hillegas
The Tuning Guide section titled "LIKE transformations" describes
transformations and optimizations which Derby performs on LIKE expressions in
order to avoid full table scans. These transformations/optimizations are
disabled when using territory-based collations. See DERBY-3854. The Tuning
Guide does not mention this fact but it is likely that this information would
be very useful to customers and tech support engineers. The "LIKE
transformations" section in the Tuning Guide should be changed to mention that
LIKE transformations/optimizations are disabled when using territory-based
collations.
