possible bug in packages.debian.org

[mop <mop2bky4mz5tyjwa8ersp7hrg5u9qn@gmail.com>]

Hi folks,

 I dont know if this is the right place to post about this, but with my
 limited english I will try.
 Let me know if there is a more adequate place.

 I think there is a bug in:
packages.debian.org

 I use it (sporadically, I am a slackware guy) for testig some software
 (for first impressions, when it is dificult to compile in a i686
 machine).

 I already wrote about 4 scripts since 2008 to use that site.These
question questions are since ever, but today I wrote this post.

 Recently I have tried (quicly) apt-get but is it much hard to set a
 RootDir in some point different from real root dir, for not disturbing
 my system.

 I am very confortable parsing web pages when the web site is OK.

 The essence of my all cited scripts is, I seed an element name and the
 script downloads and install all the dependences based on the capture
 error when trying to run th element (as an human being does).

 A practical and recent case as example, I started my fourth script on
 April 04 2016, experimenting with WireShark:

 RUN=wireshark-gtk
 STDOUT: wireshark-gtk: command not found

 wget go to (paths ending with the keyword):
https://packages.debian.org/search?suite=sid&arch=any&searchon=contents&keywords=wireshark-gtk

 And Get:
 Sorry, your search gave no results
 You have searched for paths that end with wireshark-gtk in suite
 jessie, all sections, and all architectures.

 But if wget go (manually) to (Package names only):
https://packages.debian.org/sid/i386/wireshark-gtk/filelist

 The Result is:
 /usr/bin/wireshark-gtk
 /usr/share/applications/wireshark-gtk.desktop
 /usr/share/doc/wireshark-gtk/README.Debian
 /usr/share/doc/wireshark-gtk/changelog.Debian.gz
 /usr/share/doc/wireshark-gtk/changelog.gz
 /usr/share/doc/wireshark-gtk/copyright

 Another problem is instability about results. The same query in
 different momments result in different results (usually result or no
 result). For me this is randomic and I cannot give examples at the
 momment.

 How i get credible results for package contents?

 Thanks a lot.

 PS: Is the a more logical way to do what I intend?
