About Google Search Filter

This extension is mainly targeted at developers who run API or problem focused searches over and over again. There are usually a handful of sites whose results we prefer, and a handful of sites whose results are poor or worthless.

Google Search Filter allows you to specify (in developer-friendly fashion) sites whose results you would like see highlighted and sites whose results you never want to see.

In case you use multiple installations of Chrome, this extension allows you to sync your configuration across all installations.

Here is a sample configuration:

# Make these domains stand out in results
+en.wikipedia.org
+stackoverflow.com
+github.com
+api.rubyonrails.org
# SPAM - never show these results
experts-exchange.com
# Pull filters from external source

To avoid littering the GUI with buttons, the Google Search Filter button only appears when running searches on Google.

THIS EXTENSION IS IN NO WAY AFFILIATED WITH GOOGLE
