> 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.
