Package: apt
Version: 1.8.2.1
Severity: important

Hi,

running `apt-cache search libstdc++5` on a fresh minimal system yields an empty
result. This behaviour is inconsistent with processing of command-line
arguments of the sub-commands pkgnames and show.


Environment:
- minimal buster
- sources.list: deb http://ftp.de.debian.org/debian buster main


This behaviour occurs on jessie through sid.


Here are some example commands an their respective outputs:

---------8<----------------------------
# apt-cache search libstdc++5

# apt-cache search libstdc\+\+5

# apt-cache search libstdc\\+\\+5
libstdc++5 - The GNU Standard C++ Library v3

# apt-cache search "libstdc++5"

# apt-cache search "libstdc\+\+5"
libstdc++5 - The GNU Standard C++ Library v3
--------->8----------------------------




However, the pkgnames and show sub-commands are not affected:


---------8<----------------------------
apt-cache pkgnames libstdc++5
libstdc++5

# apt-cache show libstdc++5
Package: libstdc++5
Source: gcc-3.3 (1:3.3.6ds1-30)
Version: 1:3.3.6-30
Installed-Size: 1128
[...]
--------->8----------------------------


Let me know if you need more info.

Thanks
Daniel

The behavior is correct, search takes a regular expression. Eventually
it should take patterns like other commands, but still default to a regular
expression - whereas the other commands, not being search commands, expect
names by default (this is how aptitude behaves).

This is somewhat inconsistent and unexpected, but it's what it is, and it's
documented as such.
