问题描述

我正在使用Lucene .NET 假设我只想返回从结果100开始的50个结果，那我该怎么做呢? 我已经搜索过文档，但没有找到任何东西.有什么我想念的吗?

I am using Lucene .NET Let's say I want to only return 50 results starting at result 100, how might I go about that? I've searched the docs but am not finding anything. Is there something I'm missing?

推荐答案

我假设您这样做是出于分页的目的.通常在Lucene实现(包括Solr)中完成此操作的方式是，只需简单地正常执行查询，但仅实际为您感兴趣的结果加载存储的数据.

I assume you are doing this for the purpose of paging. The way this is normally done in a Lucene implementation (including Solr) is by simply executing the query normally, but only actually loading the stored data for the results you are interested in.

在典型的分页方案中，这可能意味着多次执行相同的查询，这似乎是对资源的浪费，但是在系统缓存和Lucene缓存的帮助下，情况还不错.好处是无状态，这使您可以扩展.

In a typical paging scenario, this may mean executing the same query multiple times, which may seem like a waste of resources, but with help from the system cache and possibly Lucene's caching it's not so bad. The benefit is statelessness, which allows you to scale.
