FieldComparator.getLeafComparator介绍

[英]Get a per-segment LeafFieldComparator to collect the given org.apache.lucene.index.LeafReaderContext. All docIDs supplied to this LeafFieldComparator are relative to the current reader (you must add docBase if you need to map it to a top-level docID).
[中]获取每段LeafFieldComparator以收集给定组织。阿帕奇。卢森。指数LeaderContext。提供给此LeafFieldComparator的所有docID都是相对于当前读取器的（如果需要将docBase映射到顶级docID，则必须添加docBase）。
