無法通過盧克

Question

編輯Solr的字段我用盧克瀏覽一些Solr的指標，當我嘗試「重建&編輯」浮點型字段在我的文檔，然後選擇「刪除舊&添加」我得到一個異常：

沒有其他消息爲什麼我得到NullPointerException。我正在使用Solr 3.4創建的一些索引運行最新的Luke 3.5。任何想法還有什麼可能是錯的......？

爲了安全起見，我已經停止Tomcat，並且確保可以從運行Luke的用戶編輯索引文件（嘗試排除索引文件中的問題可能是用戶權限問題的情況）

Answer 1

我會一直使用Solr/Lucene和Luke完全相同的版本。這一點尤其重要，因爲你正試圖改變盧克的指數。它可以寫出Solr/Lucene無法讀取的版本。
