The open source project strus provides a collection of C++ (C++98) libraries and command line tools for building a full-text search engine. What makes strus unique compared with other open source search engines like Xapian,Lucene or Sphinx is the modeling of expressions for matching structures as ...

Furthermore this model empowers strus with great capabilities of extracting information from expression matches for intelligent feature selection or even query answering. [Less]
