“apt-cache search exchange”

Did you try ``axi-cache search exchange`` (from the package ``apt-xapian-index``)?

The first result I have is

100% evolution-mapi - Exchange support for the Evolution groupware suite

which may or may not be what you were actually looking for, but usually is quite more accurate for searches where you don't already know the name of the program, expecially if you also add tags to the searc.

As for the interesting results, the one above gave me 359 results, so I expect that they are also there, just at the bottom :)
