Not quite, but more or less.

That's pretty much it, yes, and it works 99% of the time. However, for
one reason or another it might not always be absolutely reliable:
occasionally packages have been aggregated or split, or are using an
older naming scheme, or whatever.

If I wanted something absolutely reliable, I would apply s,::,/,g
instead and use either 'auto-apt search -f' or 'apt-file search'. (Both
require an update step as root every so often.)
