增量索引，其实就是增加的内容，例如：存款有100块，今天挣了10块，这10块就是增量了
分布式索引，可以这样理解，想开公司钱不够，需要向很多人借钱。也就是把大家钱集中一起使用。
一，测试表和数据

}
三,插入数据，并且更新增量索引
1,插入数据
mysql> INSERT INTO orders(user_id, product_name, summary) VALUES ("1311895266", "我了个XX", "苛夺asdfasdfasdf"),
("1311895267", "iasdfasdf", "好苛夺花样百出顶戴要");
2,更新增量索引
代码如下 /usr/local/sphinx2/bin/indexer --config /usr/local/sphinx2/etc/sphinx.conf --rotate moreorder更新了增量索引后，新增的二条数据在增量索引中，而不在主索引中。
sphinx_rotate更新增量索引
sphinx_rotate更新增量索引
mysql> select * from moreorder where match("张"); //在增量索引中
+------+------------+-----------+-------------+--------------+
| id | user_id | username | create_time | product_name |
+------+------------+-----------+-------------+--------------+
| 13 | 1311895266 | 张三疯 | 0 | 我了个XX |
| 14 | 1311895267 | 张四疯 | 0 | iasdfasdf |
+------+------------+-----------+-------------+--------------+
2 rows in set (0.00 sec)
mysql> select * from myorder where match("张"); //主索引没有
+------+------------+------------+-------------+----------------+
| id | user_id | username | create_time | product_name |
+------+------------+------------+-------------+----------------+
| 9 | 1311895262 | 张三 | 1406823894 | tank is 坦克 |
| 10 | 1311895263 | tank张二 | 1406823894 | tank is 坦克 |
| 11 | 1311895264 | tank张一 | 1406823894 | tank is 坦克 |
| 12 | 1311895265 | tank张 | 1406823894 | tank is 坦克 |
+------+------------+------------+-------------+----------------+
4 rows in set (0.00 sec)
解决这个问题，有二个办法，一个利用分布式索引，一个把增量索引和主索引进行合并
四，sphinx分布式索引配置
1,修改sphinx.conf ，加上以下内容
{
type = distributed
local = myorder //本地
local = moreorder //本地
# agent = 192.168.10.103:9313:myuser //远程
agent_connect_timeout = 1000
agent_query_timeout = 3000
}
重新启动sphinx
2,插入新的数据，并更新增量索引，根上面一样，就不多说了。
3,测试sphinx 增量
+------+------------+------------+-------------+----------------+
| id | user_id | username | create_time | product_name |
+------+------------+------------+-------------+----------------+
| 9 | 1311895262 | 张三 | 1406823894 | tank is 坦克 |
| 10 | 1311895263 | tank张二 | 1406823894 | tank is 坦克 |
