SolrNet.Exceptions.SolrConnectionException在Sitecore 8.1 Upd1切換到SOLR之後

Question

我已經將我的Sitecore 8.1站點從Lucene切換到SOLR，如link所示。

一切都很好，直到我重建我的索引。除了sitecore_master_index和sitecore_core_index之外，它們都成功重建。他們都給出了類似的錯誤，我需要做些什麼來解決它？

Answer 1

看起來像問題是與_da後綴這是後綴爲索爾的丹麥文本字段。

先嚐試添加，然後從控制面板中刪除丹麥語「da」語言到Sitecore並重新索引。

對於core數據庫，從/sitecore/system/languages/節點刪除不必要的語言core db。

Answer 2

似乎在Sitecore 8.0中，它生成的Solr Schema在schema.xml輸出（在您引用的博客鏈接中提到）中添加了各種語言特定的字段映射（在<fields>下）。

在8.1更新1中，這些字段映射由於某種原因而消失，您將留下Solr錯誤。我注意到這個問題審查的報告指出，SOLR日誌後：

.SolrException: ERROR: [doc=sitecore://core/{0b511b3d-c6eb-4284-aa75-c80fdca93db2}?lang=ja-jp&ver=1&ndx=**sitecore_core_index**] unknown field 'click**_t_ja**' 

添加以下字段映射（再次提及你的blog link）回Solr的Schema.xml文件和Solr曾在這一點上。
