This might just be me being silly but I can find how to do it,
I am building a website for cooker elements.
So I want a customer to be able to search cooker 1234 element.
When the part is found it displays image, part description ect but I want it to no show the 1234 bit.
so if you understand what im talking about the same element fits cooker 1235 1236 1237 ect but I dont want anyone to be able to seal my list of models.
hopefully you understand what im trying to say.
If I correctly understood you needs you can achieve them by creating a new product attribute.
Then make it used in search, but not visible on in catalog pages in front-end properties.
