自定義Sitecore Solr索引計算字段返回錯誤值

我有一個名爲Terms的計算字段。該字段將Sitecore將multilist字段存儲的guid值列表讀取爲逗號分隔的字符串值。當我觸發索引重建並設置斷點時，我可以看到代碼按預期執行任務，但由於某種原因，在索引中，該值仍然以guid字符串數組形式存儲。我不知道斷開連接的位置。自定義Sitecore Solr索引計算字段返回錯誤值

檢查的Solr以及配置查詢返回的XML，我可以看到的條款場被存儲，像這樣：

<arr name="terms_t"> 
    <str>b7ba58ef002b4554808a1d423ca574d8</str> 
    <str>95680bf346d142aeb0d8f189300ea3f2</str> 
</arr>

下面你可以看到用於填充計算字段

namespace ASHPEngine.ComputedFields 
{ 
    public class Terms : Sitecore.ContentSearch.ComputedFields.IComputedIndexField 
    { 
     public object ComputeFieldValue(IIndexable indexable) 
     { 
      Assert.ArgumentNotNull(indexable, "indexable"); 
      var scIndexable = indexable as Sitecore.ContentSearch.SitecoreIndexableItem; 
      if (scIndexable == null) 
      { 
       return false; 
      } 
      if (String.Compare(scIndexable.Item.Database.Name, "core", System.StringComparison.OrdinalIgnoreCase) == 0) 
      { 
      return false; 
     } 
     if (!scIndexable.Item.InheritsFrom(IBaseArticleConstants.TemplateName)) return String.Empty; 
     var termsField = scIndexable.GetFieldByName(INewsConstants.TermsFieldName); 
     { 
      var retval = new StringBuilder(); 
      var terms = termsField.Value.ToString().Split(new[] { '|' }, StringSplitOptions.RemoveEmptyEntries).ToList(); 
      foreach (var id in terms) 
      { 
       var termItem = scIndexable.Item.Database.GetItem(new ID(id)); 
       retval.Append(termItem.Name + ", "); 
      } 

      return retval.Length > 0 ? retval.Remove(retval.Length-2, 2).ToString() : string.Empty; 
     } 
    } 

    public string FieldName { get; set; } 
    public string ReturnType { get; set; } 
}

我能夠通過完全刪除返回類型，像這樣以解決此問題：

<field fieldName="terms">mydll.ComputedFields.Terms, mydll</field>

這很酷:) –

嘗試更改計算字段的返回類型是字符串，而不是文本：

<field fieldName="terms" returnType="string">mydll.ComputedFields.Terms, mydll</field>

文本返回類型確保充分字符串被返回，而字符串返回類型會得到標記，這是不是打算 – Tyshun
