@zhangbaodan >Create an IndexReader from the IndexWriter during each search. This ensures that the IndexReader can see the new data in the IndexWriter and the data on the disk. Here is the corresponding code You don't need to recreate `IndexReader` from the `IndexWriter` during each search. Use the same `IndexReader` over and over that you initially obtained from `IndexWrite.GetReader()` and then call `searcherManager.MaybeRefresh()` before each search is performed. That's all that's needed to ensure the `IndexReader` can see the new data that the `IndexWriter` has written. `searcherManager.MaybeRefresh()` is about "Visibility" and commit is about "Durability". So when you call `searcherManager.MaybeRefresh()` the `IndexReader` will see the data even if you haven't called commit yet. `searcherManager.MaybeRefresh()` causes you to see the data, commit causes the data to be written to disk and committed to the index. They each work totally independently of each other. -- This is an automated message from the Apache Git Service.
