Actually i may have explained that wrong, I have the postal codes in the description box. i also have some titles with numbers ex. 3M Inc. when I do a search for 3M nothing comes back even though 3M exists in the database. :/
I believe searches only work on strings of text 3 or more characters in length.
I think I saw something on this board not too long ago that discussed a hack to allow two character searches. Sorry, don't remember the subject line of the thread, however...
