The problem isn't unique to the BBB/Debian, I've found quite a few
other people with similar issues where parts of apt take a very long
time.
The time taken seems to relate to how many hits there are in the
search! If you search for something that doesn't exist it takes (on
my BBB) about 30 seconds:-
chris@beaglebone$ time apt search xyzabc
Sorting... Done
Full Text Search... Done
real 0m27.532s
user 0m26.315s
sys 0m1.035s
Searching for something that has three hits takes longer:-
chris@beaglebone$ time apt search xvile
Sorting... Done
Full Text Search... Done

Searching for just 'vile' produces quite a lot of hits because there's quite a
few packages
with the word 'privilege' in them, so it takes around four minutes.
A workaround is to use 'apt-cache search' instead:-
chris@beaglebone$ time apt-cache search vile
