You are mixing terms. I didn't say you could type '\b' in the search box and have it work. I said that there was a way, using regex, that one can check for word boundaries. This was in reply to the statement "There is no regex capability which would allow you to specify e.g. word boundaries.".

There certainly is such a regex capability. There is not, however, a way to use that capability in the current incarnation of Super Search. The reason for this is explained by tye in a node below.
