The Tuning guide should mention that LIKE transformations/optimizations are 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.
