保存项目时 Sitecore ContentSearch 重复索引

Question

我已经为我们的应用程序实现了一个索引，该索引应该从主数据库上的项目存储桶中索引我们的项目，但似乎每次更新和保存项目时(未发布，因为索引在主数据库上工作)为该项目创建了一个附加索引，这意味着该项目的另一个搜索结果。
重新生成索引后似乎没有问题，存储桶中的每个项目都被索引一次。 我正在为下面的搜索功能添加索引配置:

Answer 1

Lucene 通过其唯一的 ID 来识别索引，即 _uniqueid <fieldNames> 中的字段部分

由于您要创建自己的/单独的索引配置，因此需要在 fieldNames 部分中添加该字段部分，以便它能够识别索引。

所以应该是这样的

<fieldNames hint="raw:AddFieldByFieldName">
    <field fieldName="_uniqueid" 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>
    <!-- Your custom Fields -->
</fieldNames>
