Revision history for KinoSearch

0.30_07  2009-08-30

  Bugfixes:

    * Revisit the bug in IndexManager's recycle().  The 0.30_06 fix attempt
      had made it manifest less often, but had not completely eliminated it.
    * Throw an error in Indexer if recycle() returns duplicated segments.


0.30_06  2009-08-17

  Bugfixes:

    * Solve a fencepost error in IndexManager's recycle() method which could
      cause document duplication and lost deletions.


0.30_05  2009-08-06

  Features:
    
    * Support for near-real-time indexing.

  New public classes:

    * KinoSearch::Index::IndexManager
    * KinoSearch::Index::BackgroundMerger
    * KinoSearch::Index::DeletionsWriter
    * KinoSearch::Obj::Err
    * KinoSearch::Store::LockErr

  New documentation:

    * KinoSearch::Docs::Cookbook::FastUpdates

  API changes:

    * KinoSearch::Indexer
      o new() - param "lock_factory" replaced by param "manager"

    * KinoSearch::Index::IndexReader
      o open() - param "lock_factory" replaced by param "manager"

    * KinoSearch::Index::SegReader 
      o get_seg_num() - added.
      o get_seg_name() - added.

    * KinoSearch::Highlight::Highlighter
      o Three dots replaced by Unicode ellipsis.

    * KinoSearch::Store::Lock
      o Now an abstract class.
      o new() 
        * Now an abstract constructor.
        * param "agent_id" renamed to "hostname".
      o get_agent_id() - replaced by get_hostname().
      o request() - added.
      o shared() - added.

    * KinoSearch::Store::LockFactory
      o new() - param "agent_id" renamed to "hostname"
      o make_shared_lock() - Now returns a Lock (instead of a SharedLock).

  Redacted:

    * KinoSearch::Store::SharedLock

  Moved:
  
    * KinoSearch::Util::BitVector -> KinoSearch::Obj::BitVector.
      (Compatibility subclass left in place for now.)

  Bugfixes:

    * Fields with empty strings could produce corrupt Lexicons.
    * Segment data files (cf.dat) over 2 GB could cause search-time crashes.

  Compatibility:

    * File-format compatible with 0.30_04.


0.30_04  2009-07-05

  Bugfixes:
 
    * Stemmer had been malfunctioning, producing incorrect stems in some cases
      and bailing out with "invalid UTF-8" errors in others.  Bug found and
      solution proposed by Nick Wellnhofer.

  Features:

    * Memory mapping implemented for Windows, so now that platform gets fast
      Searcher opens and minimized search-time process memory footprint too.

 Compatibility:

    * Indexes that utilize Stemmer must be regenerated.

0.30_03  2009-07-03

  Bugfixes:

    * Fix a problem in SortCollector that led to ranking errors for some
      documents.
    * Eliminate a symbol conflict with MSVC.

0.30_02  2009-06-29

  API Changes:

    * KinoSearch::Indexer
      o new() - "schema" argument now required only at index creation.
    * KinoSearch::QueryParser::QueryParser - ancient compatibility stub
      redacted, use KinoSearch::QueryParser instead.

  Bugfixes:
  
    * Various C compatibility tweaks for Solaris, PowerPC Linux, etc. 

  Compatibility:

    * Index version bumped.

      o new() - takes new param "rules", an array of SortRules.
      o add() - removed.

    * KinoSearch::Search::TermQuery
      o new() - now takes "field", and "term" (which is a string rather than a
        Term object as before).

  Subclassing improvements:

      in pure-Perl subclasses are automatically detected and invoked as
      callbacks by the the internal KS object engine.)

  Significant internal changes:

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
    * KinoSearch::Search::Similarity
    * KinoSearch::Contrib::LongFieldSim

  New documentation:

    * KinoSearch::Docs::NFS

  Removed classes:

    * KinoSearch::Document::Doc

    * KinoSearch::Search::Hit

  Renamed classes:

    * KinoSearch::Store::InvIndex    => KinoSearch::Store::Folder

    * KinoSearch::Store::RAMInvIndex => KinoSearch::Store::RAMFolder

  Updated documentation:

    * KinoSearch::Docs::FileFormat
    * KinoSearch::Docs::Tutorial

          changed.

        can be accomodated using results of prior search.
      o fetch_hit() - Removed.
      o create_excerpts() - Now puts multiple excerpts under $hit->{excerpts}

        set_end_offset(), get_end_offset(), set_pos_inc(), get_pos_inc - All
        removed. 

  Internal changes:

    Large-scale refactoring has taken place.  The most significant 
    changes are...

    * 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.

0.15 2006-12-04
  * Remove dead lock files when possible (with a warning), rather than failing
    outright.  (Credit to Matthew O'Connor, Luke Closs, Socialtext for
    providing initial implementation and test.)
  * Fix package name glitch in SearchClient.

0.14 2006-11-12 
  * Add MultiSearcher, SearchServer and SearchClient.

0.13 2006-08-19
  * Fix "negate operator" bug in QueryParser.
  * Allow multiple fields to be spec'd for QueryParser.
  * Add Finnish stoplist.
  * Add ExtUtils::ParseXS and ExtUtils::CBuilder as prereqs, since
    Module::Build doesn't handle C code as of 0.28.

0.12 2006-06-26
  * Modify Highlighter API
