保存项目时Sitecore ContentSearch重复索引 [英] Sitecore ContentSearch duplicate indexes when saving items

问题描述

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中的项目存储区中为我们的项目建立索引，但是似乎每次更新和保存项目时(由于该索引适用于主数据库，因此未发布)为该项目创建一个附加索引，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精确索引了一次. 我为以下搜索功能添加了索引配置:

I have implemented an index for our application which is supposed to index our items from an item bucket on the master database, but it seems that each time an item is updated and saved (not published, since the index works on master) an additional index is created for that item, which means another search result for the item.
After regenerating the indexes there seems to be no issue, each item in the bucket is indexed exactly once. I'm adding the index config for the search functionality below:

推荐答案

Lucene通过其唯一ID(即<fieldNames>部分中的_uniqueid字段)识别索引.

Lucene recognises the index by its unique id which is the _uniqueid field in the <fieldNames> section

由于要创建自己的索引/单独的索引配置，因此需要在fieldNames部分中添加该field部分，以便它可以识别索引.

Since you're creating your own/separate indexing config, you need to have that field section added in the fieldNames section so it will recognise the index.

所以应该像

<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>
