Robyn, I'm sorry that the state codes are too short for an actual 'search'.
For now, once more posters take a moment to edit their title to add the state code to the front of the title, it should become more efficient for us in a 'visual' search. It looks like this might take a little while to "catch on". I'll update if we find a better approach.
I'll edit a few more titles to add the code so that new posters might see the trend and include it on theirs.
