You are basically suggesting that you can create with PL/SQL a better indexing system
than Oracle can??? Create an index on the table with the appropriate columns. You should
select a different table space for the index than the main data storage perferrably on a
different physical spinal on a separate controller.

If the index is extremely unique -- you may consider a hashed index
