Sitecore 搜索方面和计算字段

Question

我有 10 个文章内容项，每个文章项都有一个贡献者清单

我在编辑器中创建了一个 Contributors Facet 用于分面搜索。但是清单值被索引为字符串 id。

现在在搜索结果页面上，构面值显示为字符串 id。 我创建了一个 ComputedField 来索引显示名称

public class Contributors : IComputedIndexField
{
    public object ComputeFieldValue(IIndexable indexable)
    {
        var item = indexable as SitecoreIndexableItem;

        if (item == null || item.Item == null) return string.Empty;

        StringBuilder ContributorsNameList = new StringBuilder();
        IIndexableDataField cField = indexable.GetFieldByName("Contributors");
        if (cField != null)
        {

            var cList = cField.Value.ToString().Split(new[] { '|' }, StringSplitOptions.RemoveEmptyEntries).ToList();

            foreach (var cId in cList)
            {

                var cItem = item.Item.Database.GetItem(new ID(cId));

                if (cItem != null)

                    ContributorsNameList.Append(cItem.Name.ToString());

            }

            return ContributorsNameList;

        }

        return null;

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

和配置文件

<?xml version="1.0" encoding="utf-8" ?>
  <configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
    <sitecore>
      <contentSearch>
        <configuration>
          <defaultIndexConfiguration>
            <fields hint="raw:AddComputedIndexField">
              <field fieldName="tagsfacet" storageType="yes" indexType="untokenized">                                      Sandbox.SitecoreCustomizations.ComputedIndexFields.TagsFacet, Sandbox</field>
            </fields>
            <fields hint="raw:AddFieldByFieldName">
              <field fieldName="tagsfacet" storageType="YES" indexType="TOKENIZED"                                                          vectorType="NO" boost="1f" type="System.String"                                        settingType="Sitecore.ContentSearch.LuceneProvider.LuceneSearchFieldConfiguration, Sitecore.ContentSearch.LuceneProvider">
                 <Analyzer type="Sitecore.ContentSearch.LuceneProvider.Analyzers.LowerCaseKeywordAnalyzer,                    Sitecore.ContentSearch.LuceneProvider" />
              </field>          
            </fields>
          </defaultIndexConfiguration>
        </configuration>
      </contentSearch>
    </sitecore>
  </configuration>

但现在同时获取 id 和名称（出现两次）

Answer 1

你需要看看BucketConfiguration.ResolveFacetValueToFriendlyName 在 Sitecore.Buckets.config 中。

<!-- RESOLVE FACET VALUE TO FRIENDLY NAME
If you are storing a field in the index that is being faceted on, it may be stored as an ID. This Setting when set to true, will try and resolve this to the friendly item name instead.            
USAGE: In an environment with huge amounts of items (e.g. 1 Million), this will not scale properly. -->

<setting name="BucketConfiguration.ResolveFacetValueToFriendlyName" value="false"/>

将此值修补为 true，它应该可以工作。

这样你的 ComputedField 应该会过时。
