Question

这是我的架构：

DROP TABLE products;
CREATE TABLE products (
    model VARCHAR(50) PRIMARY KEY,
    make VARCHAR(10) NOT NULL, /* symphony, autobus */
    categories VARCHAR(20), /* tv, multimedia, head-unit, speaker, graphic-equalizer,
                 base-tube, speaker-box, power-amplifier, alarm-system,
                 car-monitor, automatic-antenna, rear-view-camera,
                 emergency-light, tweeter, subwoofer
                  */
    specs TEXT,
    pic VARCHAR(100) DEFAULT 'symphony.gif',
    FULLTEXT (model, categories, specs)
) ENGINE=MyISAM;

以下是我数据库中的一些数据：

INSERT INTO products (MODEL, SPECS, CATEGORIES, PIC, MAKE) VALUES ("SY-2450U", "<li>Front AUx IN</li><li>CD/MP3/WMA playback</li><li>MP3 folder and file display</li><li>MP3 track/file</li> <li>4 channels x 40W MAx power output</li><li>Rotary volume encoder</li><li>4-band EQ (Classic, pop, rock, flat) </li>","head-unit","SY-2450U.jpg", 'symphony');

这是我的查询和输出（没有意义）：

    mysql> SELECT MATCH (model, specs, categories) AGAINST ('mp3' IN NATURAL LANGUAGE MODE) AS relevance, categories, model, pic FROM products WHERE make='symphony' AND MATCH (model, specs, categories) AGAINST ('mp3' IN NATURAL LANGUAGE MODE);
Empty set (0.00 sec)

MYSQL匹配反对不正确匹配
