SymbolHound
SymbolHound
SymbolHound is a search engine that doesn't ignore special characters. This means you can easily search for symbols like &, %, and π. We hope SymbolHound will help programmers find information about their chosen languages and frameworks more easily. SymbolHound is primarily a programming search engine. Searching for symbols is just not that useful for the average Internet user. Google could probably very easily do this, but it wouldn't make their search engine any better for the vast majority of their user base; in fact, it might make it worse. But for the small percentage of people who find themselves needing to search for special characters, Google is not useful. However, SymbolHound is a symbol search engine and is perfect for that query. -
