improve performance in a big table

["A.Burbello" <burbello3000(at)yahoo(dot)com(dot)br>]

Hi people,

I have a case and I got a doubt what should be the
best ways.

One table has more than 150 million of rows, and I
thought that could divided by state.
For each row has person ID, state and other
informations, but the search would be done only by
person ID (number column).

I can improve the query by putting index in that
column, but is there any other ways?

Thank you.
