indexing

im using this sql query to create an index:

    $query = "CREATE INDEX id_index2
            ON countries(geoname_id, name)";

but how do i update the index when new entries are added?

should i run a php script with the update query in CRON and run it every night?

is this best practice for automated index updating?
