5.0.0-beta1

This is the Elasticsearch 5.0.0-beta1 compatible release.

Features

#2233 Support for get task API
#2228 Support for multi search template API
#2228 Support for shrink index API
#2226 Support for rollover index API

#2241 Support for field_masking_span query (TY @yevhen!)
#2198 HttpClientHandler can now be modified in a custom HttpConnection when running on .NET Core. This makes it possible to validate HTTPS certs by setting ServerCertificateValidationCallback.
#2197 & #2247 Introduced an improved approach to ModifyJsonSerializerSettings for overriding Json.Net serialization settings using ISerializerFactory instead (TY @jonyadamit !)

Bug Fixes & Enhancements

#2274 Fix NRE when deserializing a mutli-bucket aggregate with an empty buckets object
#2261 Add missing routing option to FieldLookup
#2209 & #2209 Several improvements in some edgecase query DSL scenarios
#2221 Fixed issue with using a sniffing connection pool where a thread could potentially become blocked resulting in a timeout exception (TY @lostllama)
#2219 Add missing conflicts option to reindex API
#2215 Add missing term vector filters
#2215 add missing metadata on IGetResponse<T> and IMultiHit<T>
#2169 Move analyze query string parameters to request body
#2194 Removed deprecated Alias on GetAliasRequest (use Name instead) and added back the GetAliasesPointingToIndex() helper method.
#2193 Add missing collate_match option to geo_shape queries (TY @HarveyWilliams !)
#2187 Add relation to geo_shape queries and contains to geo_shape relations
#2178 Add ability to specify a custom similarity using both the fluent and object iniitalizer syntax

2.4.6

Features

• #2112 Support ReindexRethrottle when running against Elasticsearch 2.4.0, to allow throttling of longer running tasks such as Reindex and UpdateByQuery APIs.
• #2231 Support field_masking_span queries. Mapped to SpanFieldMaskingQuery to align with names of other span queries.

Enhancements

• #2279 Support overloaded UpdateByQuery() fluent methods that infer Indices and Types from generic parameter type T
• #2247 Enable conveniently overriding JsonSerializerSettings without the need to implement a custom serializer. Thanks for the PR @jonyadamit 👍

Bug Fixes

• #2261 FieldLookup now includes a Routing property. ty @seanwm
• #2178 Fix support for custom similarities using CustomSimilarity object or .Custom() fluent method on SimilaritiesDescriptor
• #2170 Resolve to the smallest whole time unit when working with DateMath as it does not support fractional values. For example, TimeSpan.FromHours(25) will serialize to 25h as opposed to round to 1d or fractional value 1.04d. ty @emmekappa
• #2209 Improve boolean combinatorial logic when dealing with bool queries with many clauses
• #2168 Mark .Highlights on SearchResponse<T> as obsolete, to be removed in 5.x. It's a leaky abstraction when searching over multiple types that contain the same document id for different types - this will throw an exception. Highlights can be enumerated using

foreach (var hit in searchResponse.HitsMetaData.Hits)
{
    foreach (var highlight in hit.Highlights)
    {
        // do something with highlightHit
        var highlightHit = highlight.Value;
    }
}

• #2125 Allow use of custom highlighters (expert level option). HighlightField now contains a CustomType string property that can be used to specify a custom highlighter. Core highlighters can still be specified using Type property.
• #2119 Allow use of per field custom similarity (expert level option). ElasticsearchPropertyAttributeBase and associated mapping methods allow the use of a custom similiarity through a CustomSimilarity string property (on attributes and mapping objects) and through the .Similairy(string) fluent mapping method. Core similarities can still be specified.
• #2274 Fix NullReferenceException when deserializing a multi-bucket aggregation that contains an empty bucket.
• #2263 Do not use IsoDateTimeConverter to handle DateTimeOffset. Take a look at #2268 for how DateTime and DateTimeOffset are serialized within NEST.

1.9.1

Features

• #2231 Support field_masking_span queries. Mapped to SpanFieldMaskingQuery to align with names of other span queries. Thanks for the PR @yevhen 👍

Bug Fixes

• #2229 Allow filter_keys string array to be specified on call to ClearCache(). The rest api json schema spec incorrectly identified this type as bool
• #2208 Use the specified Format when serializing dates within RangeFilter
• #2191 Correctly deserialize both json representations (string or array of strings) of stop words on analyzers
• #2188 Correctly deserialize templates that contain alias definitions

2.4.5

Features

• 383623e Large performance improvements to MultiGet and MultiSearch calls:
  • Cache JsonContracts per ConnectionSettings. It is recommended to share a single instance of ConnectionSettings within your application for this reason.
  • Cache Delegates per ConnectionSettings for constructing items in a MultiGetResponse
  • Cache Delegates per ConnectionSettings for constructing items in a MultiSearchResponse
  • Reuse Inferrer instance on ConnectionSettings to take advantage of cached data.
  • Reduce complexity in IUrlParameter.GetString() for IndexName and TypeName

Thanks to @antonyfrancis for raising this 👍

Bug Fixes

• fced23c Fix description for refresh on Index operation

2.4.4

Bug Fixes

• #2197 Fixed instances where modified serialization settings or custom serializers were not being respected by introducing ISerializerFactory. The old func based factory set on ConnectionSettings is now obsolete. (TY @tsliang and @mitchknife)
• #2198 HttpClientHandler can now be modified in a custom HttpConnection when running on .NET Core. This makes it possible to validate HTTPS certs by setting ServerCertificateValidationCallback.
• #2169 Analyze API parameters have been moved to the request body
• #2217 Added missing filter options to ITermVectorFilter
• #2213 Added missing meta fields to IGetResponse<T> and IMultiHit<T>
• #2219 Added missing conflicts option to ReindexOnServer
• #2221 Fixed issue with using a sniffing connection pool where a thread could potentially become blocked resulting in a timeout exception (TY @lostllama)
• #2223 Disabling _source now properly serializes as false rather than exclude: ["*"] (TY @pathikdevani)
• #2194 Deprecate Alias on GetAlias() in favour of Name

2.4.3

Bug Fixes

• #2193 Add collate_match option to the phrase suggester response (TY @HarveyWilliams !)
• #2187 Add relation and contains to geo_shape queries
• #2181 Add os.cpu_precent to node stats response (TY @TheFireCookie !)

2.4.2

Bug Fixes

#2173 Fixed UpdateByQuery from incorrectly reporting successful responses
#2159 Deprecated misnamed Field() method on SuggestContextDescriptor in favor of Path()
#2150 Fixed gzip compression when running on .NET Core
#2152 ServerError on response now properly deserializes recursive error details
#2052 Fixed exception handling issues within SimpleJson
