If I have a table with all the words that I want to complete, why would
I use something more complex than this?
SELECT word FROM words WHERE word LIKE 'foo%'
Does such a search can't use normal index?

Do you have some keywords to search for? "dictionary prefix" does not
match anything useful.
Write clearly - don't be too clever.
