　　　#这是注释信息
　　　sql_query_post 和 sql_query_post_index different?

前者是当Sphinx从数据库中得到数据后，立刻就会运行，而后者只有当索引真正成功建立后才会运行，这个区别还是很重要的。对于真正严格的程序，不应该在sql_query_pre和sql_query_post中更新增量时间，而应该在sql_query_post_index中更新增量时间。还有一个区别是sql_query_post和sql_query_post_index是存在与两个不同的tcp连接中，因为Sphinx从数据库中得到数据后去建索引，将会花费很长时间，所以它会将数据库连接关闭，等到索引建好之后，再去连接数据库，所以sql_query_post_index会在另一个连接中**/
