C＃巢 - ElasticSearch

Question

我是ElasticSearch的新手，我使用NEST來運行我的查詢。我需要能夠將X數量的過濾條件添加到我的查詢中。

現在我的查詢看起來是這樣的：

var page = new Page 
{ 
    Id = 1, 
    Name = "JR-11 Hyper black" 
}; 

var tags = new Dictionary<string, string[]> 
{ 
    { "Size", new[] { "16", "17", "18" }}, 
    { "Color", new[] { "Bronze", "Hyper Black", "Flat Black" }} 
}; 

page.Tags = tags; 

ElasticClient.Index(page, idx => idx.Index("pages")); 

var result = ElasticClient.Search<Page>(
    body => body.Query(query => query.ConstantScore(
     csq => csq.Filter(filter => filter.Term("tags.Size", "17")))) 
    .Take(1000)); 

var pages = result.Documents.ToList(); 

我的問題是與csq.Filter(filer => filter.Term("tags.Storlek")

我需要能夠增加這種過濾器的動態量。在我使用的2.3版本的文檔中找不到任何東西。

Answer 1

流利的API應該允許這樣的事情：

string[] filterTerms = { ... }; 

var result = ElasticClient.Search<Page>(
    body => body.Query(query => query.ConstantScore(
    csq => 
    { 
     var combinedFilters = csq.Filter(filter => filter.Term("tags.Size", "17")); 

     // add an additional, dynamic amount of filters 
     foreach (string filterTerm in filterTerms) 
      combinedFilters = combinedFilters.Filter(filter => filter.Term(filterTerm, ...)); 

     return combinedFilters; 
    })) 
    .Take(1000)); 

Answer 2

我結束了這一點，似乎需要:)

var result = ElasticClient.Search<Page>(
      body => body.Query(query => query.ConstantScore(csq => csq.Filter(f => 
      { 
       var ff = f.Term("tags.Size", "17"); 

       // This will be replaced with a loop containing filter terms 
       ff &= f.Term("tags.Size", "16"); 
       ff &= f.Term("tags.Size", "19"); 

       return ff; 
      }))).Take(1000)); 

謝謝您的回答是讓我在工作權方向托馬斯:)
