SySearch от Gian Klug

Firefox Add-On to search inside multiple MediaWiki instances by using the MediaWiki API and some magic to sort the results. Useful if you need to use multiple MediaWiki instances at a time.

To get started, click settings in the top right corner and add the URLs of some wikis.

Examples:
* https://wiki.archlinux.org
* https://wiki.gentoo.org
* https://en.wikipedia.org/w

After saving, you can then search for a query, for example "Linux". The results are then sorted by relevancy.
