We use the Custom Google Search tool for this search engine – unfortunately we could not find a better alternative. Google will collect data about you when you use this search engine, so be aware of that. The engine is comprised of hundreds of hand curated sources that we constantly update. They are all categorized for the ease of searching. The search engine is not meant to replace a normal search engine but to allow people to search for specific things. For example if you search for “video editor” and filter by “open source”, it will help you find an open source video editor. Or, imagine searching for a medical condition or anything scientific and sorting by “scientific papers”.
