我已经使用 FlatDataCrawler 在 Sitecore 中创建了我的自定义索引。
索引已创建,我可以在 Solr 中查看我的文档。
问题是,每当我试图在我的代码中获取这些文档时,我都会看到如下异常:
Object reference not set to an instance of an object.
在 sitecore 日志文件中,我看到了这个警告:
ManagedPoolThread #4 14:29:09 INFO Solr Query - ?q=*:*&rows=1000000&fq=_indexname:(products_index)&wt=xml
ManagedPoolThread #4 14:29:09 WARN Could not map index document (field: _uniqueid; Value: fae308d2-233f-4f7f-a4fd-9d880e42ff13) - Object reference not set to an instance of an object.
这是我的索引配置:
<?xml version="1.0" encoding="utf-8" ?>
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:role="http://www.sitecore.net/xmlconfig/role/" xmlns:search="http://www.sitecore.net/xmlconfig/search/">

<param desc="core">$(id)</param>

<crawler type="Feature.ProductsIndex.Crawlers.CustomOrderCrawler, Feature.ProductsIndex" />
</locations>
</index>
</indexes>
</configuration>
</contentSearch>
</sitecore>
</configuration>
这是我的代码:
using (var searchContext = ContentSearchManager.GetIndex("products_index").CreateSearchContext())
{
int count = searchContext.GetQueryable<SearchResultItem>().Count(); //This works
var results = searchContext.GetQueryable<SearchResultItem>().ToList(); //Exception here!
}
