6.2.1 (2018-07-03)

6.2.0 (2018-07-03)

Backwards incompatible change - DocType refactoring.

In 6.2.0 we refactored the DocType class and renamed it to Document. The primary motivation for this was the support for types being dropped from elasticsearch itself in 7.x - we needed to somehow link the Index and Document classes. To do this we split the options that were previously defined in the class Meta between it and newly introduced class Index. The split is that all options that were tied to mappings (like setting dynamic = MetaField('strict')) remain in class Meta and all options for index definition (like settings, name, or aliases) got moved to the new class Index.

You can see some examples of the new functionality in the examples directory. Documentation has been updated to reflect the new API.

DocType is now just an alias for Document which will be removed in 7.x. It does, however, work in the new way which is not fully backwards compatible.

  • Percolator field now expects Query objects as values
  • you can no longer access meta fields on a Document instance by specifying ._id or similar. Instead all access needs to happen via the .meta attribute.
  • Implemented NestedFacet for FacetedSearch. This brought a need to slightly change the semantics of Facet.get_values which now expects the whole data dict for the aggregation, not just the buckets. This is a backwards incompatible change for custom aggregations that redefine that method.
  • Document.update now supports refresh kwarg
  • DslBase._clone now produces a shallow copy, this means that modifying an existing query can have effects on existing Search objects.
  • Empty Search no longer defaults to match_all query and instead leaves the query key empty. This is backwards incompatible when using suggest.

6.1.0 (2018-01-09)

  • Removed String field.
  • Fixed issue with Object/Nested deserialization

6.0.1 (2018-01-02)

Fixing wheel package for Python 2.7 (#803)

6.0.0 (2018-01-01)

Backwards incompatible release compatible with elasticsearch 6.0, changes include:

  • use doc as default DocType name, this change includes: * DocType._doc_type.matches method is now used to determine which DocType should be used for a hit instead of just checking _type

  • Nested and Object field refactoring using newly introduced InnerDoc class. To define a Nested/Object field just define the InnerDoc subclass and then use it when defining the field:

    class Comment(InnerDoc):
    body = Text()
    created_at = Date()

class Blog(DocType):
    comments = Nested(Comment)

  • methods on connections singleton are now exposed on the connections module directly.

  • field values are now only deserialized when coming from elasticsearch (via from_es method) and not when assigning values in python (either by direct assignment or in __init__).

5.4.0 (2017-12-06)

  • fix ip_range aggregation and rename the class to IPRange. Iprange is kept for bw compatibility
  • fix bug in loading an aggregation with meta data from dict

  • adding exclude to Search
  • fix metric aggregation deserialization
  • expose all index-level APIs on Index class
  • adding delete to Search which calls delete_by_query API

5.1.0 (2017-01-08)
