I have various products on my websites, all with product numbers such as (3KA, 400DKP, etc). I want make it so that if a person places a space inbetween any part of the PN, the search will know to try the query without spaces. Example: the PN is 3KA but the user searches for 3 KA. currently the search will not find the 3KA because it is not 1 word. how can I fix this?
