  • Relevance tuning - Sphinx offers extensive options to tune search relevance and promote the most important documents to the top of the search results.
  • Scalability - Sphinx scales horizontally across multiple servers to handle heavy query loads.
  • Integration - Sphinx provides APIs for most popular programming languages allowing easy integration into new or existing applications.
  • Advanced features - Sphinx supports features like faceted search, grouping/clustering, snippets, sorting etc out of the box.

Due to its speed, flexibility and ease of use, Sphinx has been integrated into many large web properties like craigslist, reddit, Stack Overflow etc. It can handle both small niche websites and extremely high traffic sites effectively.
