1·But in the case of users, we know that the table will quickly grow into the millions of users, and will be ineffective without an index on frequently searched columns.
但从用户这方面来看，我们知道该表将会很快具有数百万的用户，如果在经常搜索的列上没有索引，该表的效率会很低。
2·The query is typically specified by entering search text (sometimes with wildcard functionality) for one or more of the fields in the object to be searched.
通常通过给对象中要搜索的一个或多个字段输入搜索文本(有时候支持通配符功能)来指定查询。
3·If the string to be searched is not found and neither argument is null, the result is 0.
如果没有找到搜索字符串，并且参数都不为空，则所得的结果是0。
4·If this configuration file is not present, the next searched for is C0A8000, and so on.
如果这个配置文件不存在，第二个搜索就查找C0A8000，依次类推。
5·Each node in the tree is searched in comparison to the node being freed, and if it adjoins any other node in terms of the address, it is joined to that node.
搜索树中的每个节点并与释放的节点进行比较，如果释放的节点的地址与任何其他节点相邻，它就与那个节点合并。
