每一個項目RavenDB

Question

任何方式，我可以得到RavenDB的每個Nth文檔？

我想是這樣的，在here所見：

Query<MyDoc, MyDoc_Index>().Where((x, i) => i % nStep == 0); 

我得到以下錯誤：

Could not understand how to translate '(i % 1000)' to a RavenDB query. Are you trying to do computation during the query? RavenDB doesn't allow computation during the query, computation is only allowed during index. Consider moving the operation to an index.

我沒有問題，如果添加一個我減少對我的索引不得不。謝謝！

您是否嘗試過使用.Skip()方法？

MyDoc nthValue = session.Query<MyDoc, MyDoc_Index>().Skip(nStep-1).FirstOrDefault();
