Bug#883713: packages.debian.org: search contents of packages will not find full path
Go to https://packages.debian.org/index and enter
/etc/bluetooth/main.conf under "Search the contents of packages".
Ensure default "packages that contain files named like this" is
selected, distribution stretch, architecture any, and press search. The
result is "Sorry, your search gave no results".
If you remove "/etc", so the keyword is "/bluetooth/main.conf", you get
the expected result, file "/etc/bluetooth/main.conf" found in package
"bluez". (Just removing the leading /, as in "etc/bluetooth/main.conf"
does not work either.)
