    you could use query hints, but why bother? the query optimzer is designed
    to take advantage of the indexes when they exist.

    Try using Index Hints like this one on a Pubs DB ...

    Select * from authors With (Index (aunmind))

    You can use table hints.

    SELECT something FROM sometable WITH (INDEX(indexname_or_id))

    Look in BOL 'From' clause for more details.
