Is there anyway to stop shopify searching more than I've entered? I tried to switch prefix off by changing it from last to none, but I still can't work it out... basically, we're a car parts company, when we search ERR3340, for example, we want it to show ERR3340G but not ERR3339 because that's a totally different number. I've spoke to a few developers and they don't know if it's possible.... but I can buy an external app to do it for me so it must surely?! I don't want the app as they want $400 a month to index the products we have, and that's a lot of extra fees for something that doesn't seem like it should be this hard!!!
