NEST棄用領域包括]

Question

我剛剛更新彈性搜索從2.3.4到5.0.1，和鳥巢C＃NuGet包到最新的2.4.7

我有以下窩查詢：

 SourceFilter sourceFilter = new SourceFilter() 
     { 
      Include = Infer.Fields<Page>(p => p.Category, p => p.Title) 
     }; 

     MultiMatchQuery multiMatchQuery = new MultiMatchQuery() 
     { 
      Fields = Infer.Fields<Page>(p => p.Title, p => p.MetaDescription, p => p.Keywords), 
      Type = TextQueryType.PhrasePrefix, 
      Query = search.Term 
     }; 

     var searchQuery = new SearchRequest<Page>() 
     { 
      From = search.ResultsFrom, 
      Size = search.ResultsSize, 
      Source = sourceFilter, 
      Query = multiMatchQuery 
     }; 

     var searchResponse = client.Search<Page>(searchQuery); 

我收到以下錯誤背面由彈性：

Deprecated field [include] used, expected [includes] instead

註釋掉SourceFilter允許查詢運行通過。

有沒有不同的使用方法SourceFilter？

如果你對Elasticsearch 5.0.1，you should use a 5.x version of NEST運行; nuget上最新的5.x版本是5.0.0-rc3（預發佈），5.0.0很快就會發布。

5.x contains the Includes property on ISourceFilter表示Kulasangar highlights in his answer。

爲Include的語法應Includes代替Include根據source filtering usage。即使你上面提到的錯誤簡化了Include的錯誤語法。我不確定版本的兼容性。如果我複製你的，就應該是這個樣子：

Source = new SourceFilter() 
    { 
     Includes = Infer.Fields<Page>(p => p.Category, p => p.Title)   
    };
