FilterContainer在Elasticsearch NEST 5.0

Question

我對Elasticsearch遷移工作從1.7.1到5.0。 我修復了大部分的代碼問題升級到5.0之後，但我無法弄清楚如何改變FilterContainer在新版本中工作。

下面是我的代碼

public static List<FilterContainer> GetPriceRangeFilters(SearchListCriteria criteria, out List<FilterContainer> additionalpricefilters) 
    { 
     var pricefilters = new List<FilterContainer>(); 
     additionalpricefilters = new List<FilterContainer>(); 
     if (criteria.SearchGlobalSettings.MinimumPriceRange != null && criteria.SearchGlobalSettings.MinimumPriceRange.Length > 0) 
     { 
      const string fieldName = "itemPrices.webPrice"; 
      pricefilters.Add((new FilterDescriptor<ItemSearchEntry>()).Query(a => a.Range(n => n.OnField(fieldName).GreaterOrEquals(criteria.SearchGlobalSettings.MinimumPriceRange[0].ToString()). 
       LowerOrEquals(criteria.SearchGlobalSettings.MaximumPriceRange[0].ToString())))); 
      for (var i = 1; i < criteria.SearchGlobalSettings.MinimumPriceRange.Length; i++) 
      { 
       additionalpricefilters.Add((new FilterDescriptor<ItemSearchEntry>()).Query(a => a.Range(n => n.OnField(fieldName). 
        GreaterOrEquals(criteria.SearchGlobalSettings.MinimumPriceRange[i].ToString()).LowerOrEquals(criteria.SearchGlobalSettings.MaximumPriceRange[i].ToString())))); 
      } 
     } 
     return pricefilters; 
    } 

Answer 1

FilterContainer在NEST 2.0起，because filters and queries merged in Elasticsearch into queries不再存在，具有查詢或過濾上下文。

如果你要使用FilterContainer，使用QueryContainer然後加入到搜索時，傳遞的FilterContainer收集到bool查詢filter條款。
