Changes for version 0.20_01 - 2007-02-26

  • KinoSearch 0.20 is a major rewrite, adding many new features. It also breaks backwards compatibility in a number of ways.
  • Two key features, UTF-8 support and custom sorting, were not possible to implement while preserving backwards compatibility. Once the decision was made to proceed with them, breaking all existing installations, it made little sense to proceed by half measures, so the API has been given a significant overhaul.
  • KinoSearch has always carried an "alpha code" warning; it is being invoked for this release. While it will continue to carry the "alpha" warning for a short while longer, the point of jamming so many changes into one release is to cause disruption only once; once the code in 0.20 proves itself, hopefully no more backwards incompatible changes will be needed any time soon.
  • New behaviors:
    • KinoSearch now uses UTF-8 for all input and output, throughout the entire library. This affects many classes, but particularly those under Analysis, Highlight, and QueryParser.
    • The default scoring algorithm has changed subtly -- aggressive per-field boosting is no longer important or even desirable. The old behavior is available from KinoSearch::Contrib::LongFieldSim.
  • New public classes:
    • KinoSearch::Schema
    • KinoSearch::Schema::FieldSpec
    • KinoSearch::InvIndex
    • KinoSearch::Analysis::Token
    • KinoSearch::Search::RangeFilter
    • KinoSearch::Search::SortSpec

      • analyzer - Removed.
      • lock_id - Added.
      • o spec_field() - Removed. o new_doc() - Removed. o add_doc() - Args changed.

    • OO framework imposed on C code via boilerplater.pl, with KinoSearch::Util::Obj as the base class.
    • Charmonizer added.
    • perlapi functions and data structures replaced whenever possible.
    • Lots of classes, especially under KinoSearch::Index, reorganized around Schema and SegInfo.
    • Many tests added, removed, or revised to accomodate changes in the main library code.
    • C code moved to dedicated files.
    • Build.PL custom code moved to buildlib/KinoSearchBuild.pm
  • File Format:
    • Significantly redesigned. The most visible change is that the segments file is now encoded using YAML rather than an arbitrary binary format.
    • Old indexes cannot be read and must be regenerated.
  • Locking
    • write.lock files now located in the index directory rather than under /tmp.
    • Commit locks are no longer needed due to file format changes.
    • Stale write locks are now removed without warning.
