As with including the word "stripes" in a search where you want to omit results with stripes, including the word "mini" is only causing unnecessary confusion. The adapter that works for a Mac Mini will also work for a Macbook, as an example.

A shirt lacking stripes would never be described or labeled as a "shirt without stripes."

In the absence of that actual description, you are asking google to assume what you mean.

I would just never expect that to work very well.
