Kentico 过滤搜索中的重复项

Question

我有以下脚本来返回链接页面的搜索结果。我需要过滤掉别名页面的重复项，并按字母顺序对结果进行排序。目前，它返回主页面和别名页面，并且不对它们进行排序。

<script runat="server">
    bool hasDegree;
    bool hasCertificate;
    bool hasLetter;
    protected override void OnInit(EventArgs e)
    {
        base.OnInit(e);
        hasDegree = ValidationHelper.GetBoolean(CMS.DocumentEngine.DocumentHelper
           .GetDocuments("FCC.Credential").Path(Eval<string>("NodeAliasPath"), CMS.DocumentEngine.PathTypeEnum.Children)
           .Published().Where("CredentialType = 'D'").Count > 0, false);
           
        hasCertificate = ValidationHelper.GetBoolean(CMS.DocumentEngine.DocumentHelper
           .GetDocuments("FCC.Credential").Path(Eval<string>("NodeAliasPath"), CMS.DocumentEngine.PathTypeEnum.Children)
           .Published().Where("CredentialType = 'C'").Count > 0, false);
           
        hasLetter = ValidationHelper.GetBoolean(CMS.DocumentEngine.DocumentHelper
           .GetDocuments("FCC.Credential").Path(Eval<string>("NodeAliasPath"), CMS.DocumentEngine.PathTypeEnum.Children)
           .Published().Where("CredentialType = 'L'").Count > 0, false);         
    }

    protected string imageFilePath(string cssClass, string baseImageName)
    {
        string fileResolution = (cssClass == "desktop") ? "320x200" : "180x180";

        if (baseImageName.Trim().ToLower().EndsWith(".mp4"))
        {
            string baseName = baseImageName.Trim();
            baseName = baseName.Substring(0, baseName.Length - 4);
            return "/FCC/media/ProgramsOfStudy/Video/" + baseName + "_" + fileResolution  + ".jpg";
        }

        return "/FCC/media/ProgramsOfStudy/" + fileResolution + "_" + baseImageName;
    }
</script>

还在名为：RepeaterWithCustomQuery 的页面模板上找到了这个

Answer 1

在您的 DocumentQuery 中，添加 .FilterDuplicates()，它应该会为您删除那些重复的记录。请记住，它不会带回链接文档，只会带回主文档。

*** 更新 *** 根据更新的问题，您更新问题的查询看起来像 Kentico 生成的查询。我不确定它为什么被创建，但我将转发器的可见性设置为 false 并在页面上添加一个新的转发器并设置你认为合适的属性。然后根据需要更新 WHERE 条件。
