The bug is present in Ubuntu 16.04; apt version 1.2.10 (amd64)
$ apt-cache search --names-only ab|grep -cv ab
Furthermore, the command does not restrict to the package names even if the option suggests it does.
The following script should print 0:
$ apt-cache search --names-only ab|cut -d' ' -f1|grep -cv ab

apt-cache search --names-only gives many false positives
Status in apt package in Ubuntu:
Binary package hint: apt
The manpage for apt-cache says that --names-only should "Only search
on the package names, not the long descriptions."
And yet it frequently lists packages that do not have the search terms
in the name or short description.
Example: (bash script)
for x in ab bc de ef
echo "False positives for apt-cache search --names-only '$x':"
apt-cache search --names-only $x | grep -iv $x
I get 99 false positives, attached is the output of the above script
on my box.
I have ubuntu hardy, and I did "apt-get update" and "apt-get upgrade"
a few days ago. I don't think this bug is new.
