I have a control panel where the site owner can search for products by product number. It happens quite often though that they make a typo: BAR 2131G instead of BAR2131G (notice the space in the first one. Or instead of the G at the end they type a H (next to the G on the keyboard). I would like to return some alternative records in case something like that occur. What would be the best where clause in such a case? A wildcard LIKE % % or are there any other suggestions?

Thank you in advance
