Linux Search is a custom search engine that only searches dedicated Linux websites.
Google used to have a custom search for Linux (aka GNU/Linux) at
google.com/linux but they discontinued it on the basis that it's normally enough to add
linux as a search term. However, this custom search is useful:
- If you want to avoid spammy search results
- When searching for a rarely used term such as a model number - such searches often give hits which mention merely Linux in a sidebar or footer etc, but where the page itself is are not actually about Linux.
By narrowing the search down to only Linux-specific websites, these problems are avoided.
