The ``zope.index`` package provides several indices for the Zope
catalog.  These include:

* a field index (for indexing orderable values),

* a keyword index,

* a topic index,

* a text index (with support for lexicon, splitter, normalizer, etc.)


4.0.1 (2013-02-28)

- Added the forgotten dependency on ``six``.
  Fixes https://github.com/zopefoundation/zope.index/issues/1.

4.0.0 (2013-02-25)

- Added support for Python 3.3.

- Replaced deprecated ``zope.interface.implements`` usage with equivalent
  ``zope.interface.implementer`` decorator.

- Dropped support for Python 2.4 and 2.5.

3.6.4 (2012-03-12)

- Insure proper unindex behavior if index_doc is called with a empty sequence.

- Use the standard Python doctest module instead of zope.testing.doctest

3.6.3 (2011-12-03)

- KeywordIndex: Minor optimization; use __nonzero__ instead of __len__
  to avoid loading the full TreeSet.

3.6.2 (2011-12-03)

- KeywordIndex: Store docids in TreeSet rather than a Set when the
  number of documents matching a word reaches a configurable
  threshold (default 64). The rule is applied to individual words at
  indexing time, but you can call the new optimize method to optimize
  all the words in an index at once. Designed to fix LP #881950.

3.6.1 (2010-07-08)

- TextIndex:  reuse the lexicon from the underlying Okapi / Cosine
  index, if passed.  (LP #232516)

- Lexicon:  avoid raising an exception when indexing None. (LP #598776)

3.6.0 (2009-08-03)

- Improved test readability and reached 100% test coverage.

- Fixed a broken optimization in okascore.c: it was passing a Python
  float to the PyInt_AS_LONG() macro. This resulted in wrong scores,
  especially on 64 bit platforms, where all scores typically ended up
  being zero.

- Changed okascore.c to produce the same results as its Python
  equivalent, reducing the brittleness of the text index tests.

3.5.2 (2009-06-09)

- Port okascore.c optimization used in okapiiindex from Zope2 catalog
  implementation.  This module is compiled conditionally, based on
  whether your environment has a working C compiler.

- Don't use ``len(self._docweight)`` in okapiindex _search_wids method
  (obtaining the length of a BTree is very expensive at scale).
  Instead use self.documentCount().  Also a Zope2 port.

3.5.1 (2009-02-27)

- The baseindex, okapiindex, and lexicon used plain counters for various
  lengths, which is unsuitable for production applications.
  Backport code from Zope2 indexes which opportunistically replaces the
  counters with BTree.Length objects.

- Backport non-insane version of baseindex._del_wordinfo from
  Zope2 text index.  This improves deletion performance by
  several orders of magnitude.

- Don't modify given query dictionary in the KeywordIndex.apply method.

- Move FieldIndex's sorting functionality to a mixin class so it can
  be reused by zc.catalog's ValueIndex.

3.5.0 (2008-12-30)

- Remove zope.testing from dependencies, as it's not really needed.

- Define IIndexSort interface for indexes that support sorting.

- Implement sorting for FieldIndex (adapted from repoze.catalog/ZCatalog).

- Add an ``apply`` method for KeywordIndex/TopicIndex, making them
  implement IIndexSearch that can be useful in catalog.

- Optimize the ``search`` method of KeywordIndex/TopicIndex by using
  multiunion for the ``or`` operator and sorting before intersection for ``and``.

- IMPORTANT: KeywordIndex/TopicIndex now use IFSets instead of IISets.
  This makes it more compatible with other indexes (for example, when
  using in catalog). This change can lead to problems, if your code somehow
  depends on the II nature of sets, as it was before.
  Also, FilteredSets used to use IFSets as well, if you have any
  FilteredSets pickled in the database, you need to migrate them to
  IFSets yourself. You can do it like that:
      filter._ids = filter.f
