The result is then sent back to the Unicode client from the database, and the reply gets converted accordingly.
注意，getallpeople函数将发送一个搜索公式给NAB，以获取所有的Person文档，这等同于搜索可以操作LotusDomino数据库的客户机用户。
Notice that the getAllPeople function sends a search formula to the NAB to obtain all Person documents, which is identical to the search a client user may conduct on a Lotus Domino database.
