Conductorr

UserScript for multi-tracker search.

Installation

Install the userscript from GreasyFork.
Save conductorr.html locally and open it.

Make sure local files are accessible from userscripts in your browser:

GreaseMonkey 3: open about:config and change greasemonkey.fileIsGreaseable to true,
GreaseMonkey 4: incompatible,
TamperMonkey: open settings and enable the option named like Allow access to file URLs or Allow scripts to access local files,
Violentmonkey: works out-of-the-box.

Hints

To clear the page, clear the search input twice.
The script uses HTTPS everywhere possible. If a source reports a host error, click on its icon in the message and check, if there is a browser message about invalid certificate preventing the page from loading. If the issue is non-critical, like an expired certificate, you can add it to exceptions.
Movies support years in queries, tv shows support resolutions.
