110 60 20 one would ultimately be one I would want to show. But say a user just searched for a width of 110 and there wasn't an exact match. The search would return any results that have a width within 20 of that. So, say 112, 118, 114, 129 and so on and so forth, but only if they were in the database.
I am not quite sure about the SUM or the PRODUCT, as all of them need to be treated separately. As explained above with my example, I want the same with the other two searches, just for the database to return results that are within 20 of the search. So if you have a search of 250, 190, 80 it will find all exact matches, then display all searches that are within 20. So ranging up to 270>230, 210>170, 100>60. Not quite sure how to explain it. We could try a few different ways.
I am horrible at explaining haha. Thanks for helping.
