quicksearch: a minimalistic webservice providing search abbreviations straight from any browser's address bar

You've configured your browser to have search abbreviations for all your most-used search engines and other useful sites.
woa velocity of unladen swallow and there you are at Wolfram Alpha.

But what if you're using a friend's/colleague's browser without all that convenience?
quicksearch to the rescue: a tiny Python script that is programmable in the same way — except it runs as a webserver and is thus usable from any browser anywhere. (If you've got a domain to run it on, that is.)

That query from above would become something like jjj.re/woa/velocity of unladen swallow. Not quite as convenient as your in-browser keywords, but certainly faster than typing wolframalpha.com and waiting for 3.4 MB of website to load just so you can type in your query.

Want to check out my stock version?
There is a publicly accessible instance at jjj.re.
(The site intentionally does not perform a redirect to HTTPS to save roundtrips and thus time.)

Setup

1. Clone repo to /opt

   git clone --recursive https://github.com/n-st/quicksearch.git /opt/quicksearch
   

2. Install requirements

   pip3 install -U flask twisted
   # Optionally, for phone number analysis:
   pip3 install -U phonenumbers
   # Optionally, for MAC/OUI lookup:
   wget -O data/oui.txt http://standards-oui.ieee.org/oui.txt
   
   # On Debian, you can instead use the (slightly older) versions from the official package repository:
   apt install python3-flask python3-twisted python3-phonenumbers
   

3. Copy quicksearch.service to your systemd service directory

   cp /opt/quicksearch/quicksearch.service /etc/systemd/system
   

4. Check where pip installed twistd3 on your system, adjust path in service file if necessary

   which twistd3
   vim /etc/systemd/system/quicksearch.service
   

5. Adapt path, port, and bindhost settings to your needs

   grep Environment= /etc/systemd/system/quicksearch.service
   vim /etc/systemd/system/quicksearch.service
   

6. Enabled and start service

   systemctl enable --now quicksearch.service
   

Non-redirect functionality

Over time, quicksearch evolved to also contain a few additional features beyond mere search redirections:

• /ip
  Print the IP address from which the user is connecting:

  203.0.113.89
  

  or

  2001:db8:78a3:9889:5bd1:b3e5:bb52:ed80
  

• /mac/48-2C-6A-1E-59-3D or /oui/48-2C-6A-1E-59-3D Look up which organization this OUI is registered to.
  Also supports other formats, e.g. 48-2C-6A-1E-59-3D, 48:2C:6A:1E:59:3D, 482c6a, etc.

• /telnum/+442072343456 or /telnum/442072343456
  Print information about the phone number's origin country, region, and type:

  +44 20 7234 3456
  London, United Kingdom - fixed-line
  

• /ula
  Generate a Unique Local IPv6 Unicast Address (ULA) according to the algorithm in RFC 4193, section 3.2.2.
  The output is the network address (all host bits set to zero) of the ULA /48:

  fd6c:e2c3:fb9c::
  

Todos / Possible improvements

• Show the last-updated date of the OUI file (from file modification date)
• Support IABs in OUI lookup
• Use netaddr for MAC parsing and (fallback) OUI lookup
