Great thanks for your helpful advice and suggestions.

I intended to use the module for a web-based search function for products. So if a user types a search string that is close to one of the products, then that product name will be suggested to the user. Since more than one match may be returned, I guess I will display the matched products as suggestions.

Would that be considered appropriate in your opinion?
