Since you are selecting all fields, which in some cases is not the recommended procedure as the output could probably be reduced and so on, I don't know how many fields your query returns, hence I could not give a valid range of cache_get_row(0, 0-x, temp) lines.
If your query returns at least 5 rows, you can use index 4, sure.
