Bug#1062892: aptitude: search does not handle virtual packages if apt-xapian-index is installed

[of1]

Package: aptitude
Version: 0.8.13-5+b1
Severity: normal

Dear Maintainer,

If apt-xapian-index is installed, aptitude cannot handle searches performed
on virtual packages. For example:


$ apt policy apt-xapian-index
apt-xapian-index:
Installed: 0.54
Candidate: 0.54
Version table:
*** 0.54 500
500 http://deb.debian.org/debian unstable/main amd64 Packages
100 /var/lib/dpkg/status
$ aptitude -F "%c %p" search "?exact-name(lha)"; echo $?
1
$ aptitude -F "%c %p" search "?provides(?exact-name(lha))"; echo $?
1


Deinstalling apt-xapian-index solves the problem:


$ apt policy apt-xapian-index
apt-xapian-index:
Installed: (none)
Candidate: 0.54
Version table:
0.54 500
500 http://deb.debian.org/debian unstable/main amd64 Packages
$ aptitude -F "%c %p" search "?exact-name(lha)"; echo $?
v lha

0
$ aptitude -F "%c %p" search "?provides(?exact-name(lha))"; echo $?
p jlha-utils
p lhasa

0


Best Regards
