换汤不换药的UpdateDocuments

 

一直很好奇当初Apache曾经说的即将推出的UpdateDocuments()方法是个什么样的方法，Lucene索引的这种紧凑的文件结构如何能“允许”这个“Update”动作的发生呢？

千呼万唤始出来，不出所料，还是换汤不换药

 

    /// In either case, documents are added with {@link #AddDocument(Document)
    /// addDocument} and removed with {@link #DeleteDocuments(Term)} or {@link
    /// #DeleteDocuments(Query)}. A document can be updated with {@link
    /// #UpdateDocument(Term, Document) updateDocument} (which just deletes
    /// and then adds the entire document). When finished adding, deleting 
    /// and updating documents, {@link #Close() close} should be called.
