Follow-up to my own post:
The problem is with the '_' wildcard, but I still don't understand. My
previous examples were simplified, but here is the exact query:
SELECT * FROM words WHERE word LIKE 'Regional/North_America'
SELECT * FROM words WHERE word LIKE 'Regional North_America'
I understand the the underscore was matching a wildcard and not a literal,
but I still don't understand why the first query DOES NOT use the index on
word and the second query does.
