libswish3 1.0.0 released

I am happy to announce the 1.0.0 release of libswish3:

libswish3 is at the core of multiple Swish3 implementations, and has reached a stable enough API that a 1.0.0 release seems appropriate.

From the README:

libswish3 is a document parser compatible with the Swish-e 2.4 -S prog API. libswish3 is a C library for parsing documents into a data structure that can then be stored and searched with a variety of IR backends.

There are currently four different implementations available of Swish3.

  • swish_xapian (C++ using libxapian, included in libswish3 distribution)
  • SWISH::Prog::Xapian (Perl using Search::Xapian)
  • SWISH::Prog::Lucy (Perl using Apache Lucy)
  • SWISH::Prog::KSx (Perl using KinoSearch)

All the Perl implementations are available from CPAN. They each rely on SWISH::3 (the Perl bindings to libswish3) and the core SWISH::Prog project, a Perl rewrite of the swish-e 2.x C binary and accompanying helper scripts. The SWISH::Prog distribution includes a ‘swish3’ command line interface with options very similar to the swish-e 2.x command line tool.

Xapian, KinoSearch and Apache Lucy all offer robust UTF-8 and incremental indexing support, as well as the ability to scale to many millions of documents across multiple servers.

You can read more about Swish3 at the devel site.
