Indices (was Re: [GENERAL] query seems too slow)

By the way,

I've created a secondary index on a large table in order to
gain some speed (the index is not unique), but the "explain"
did not report any change.

What else do I have to do to actually *use* an index? The manual
only tells how to create one.

FAQ?
