Text search question

Hi Everyone,

I built a search ages ago using what i thought to be a trim function to search on everything after a specified character. I can't seem to find the right function for this.

I have a series of part numbers that prefix with 1 or 2 characters and then a - then the following numbers (there are always 5 trailing digits)

I want our sales team to be able to come in and type in the last 5 digits and bring back the results matching on those five digits alone. Would some one please give me an example, or tell me what function i should be using?

Thanks!
