But what is the function of *-* in the search string ?

Wildcards. Google (alone, AFAIK) allows those.
When the results page appears, the words that appear in the phrase
where the asterisks are[1] will be highlighted
(along with the requested text).

....and, of course, the day after I post the link,
Google stops indexing the page. 8-(

Note also that when properly rendered on a schematic,
a CA device will have a nose-to-nose symbol reprentation.

[1] A hyphen is a valid word separator (as is a period).
