With the lastest version of SQLite (version 3) and if circumstances
are just right, LIKE will use an index.

Unfortunately that does not make any difference if the
search is made using 'LIKE' because SQLite will ignore the
index and will perform a full table scan. See 5.5.1 at:

The document refers to version 2.8.6 (10 September 2003), a lot of
changes occurs in sqlite since that version.
Yes, I know it's for an old version, but the part I was referring was
ONLY to using the 'LIKE' with a index. Does SQLite currently uses an
index (if present) when the search is made with 'LIKE' or performs a
full table scan?
