This blog says:

‘AJD’, ‘AJDx’, ‘ADJ/x’, ‘xw’ – These are also proximity operators which are the same as NEAR, but matches must be in the same order.

However, when I searched in Google patent site with the following keywords:

TI=("smart" ADJ/2 "ring")

The result does not match with what the site claimed. I want all the results where title must contains both "smart" and "ring" orderly within range 2 words. What should be the correct query and why?

Saying unexpected results because it also included a title like: "Smart-home device installation guidance"

    I've tried your example and can confirm the feature doesn't work. All I can say is that Google Patents, while convenient, isn't the best site for free patent searching. I prefer Lens. lens.org/lens

    Not an expert, but the documentation is pretty good. support.lens.org/knowledge-base/proximity-search

    Not a problem. Lens might not do exactly what you are looking for, but I find it generally more robust than Google Patents.
