Question

If I have a table on my DB called product_tags with 2 fields: tag_id and tag_name

Here is the schema:

CREATE TABLE `product_tags` (
 `tag_id` int(11) NOT NULL auto_increment,
 `tag_name` varchar(255) NOT NULL,
 PRIMARY KEY  (`tag_id`),
 UNIQUE KEY `tag_name` (`tag_name`)
) ENGINE=MyISAM AUTO_INCREMENT=84 DEFAULT CHARSET=utf8

Say here some tags in it:

• yellow gold
• yellow diamond
• white gold
• rose gold
• band
• diamond
• blue diamond
• pink diamond
• black diamond

And I want to do a search on the string “yellow gold diamond band“

I only want to pull the following tags:

• yellow gold
• band
• diamond

Because only those tags are exactly in the string. yellow and diamond are both in the string but not together so the yellow diamond tag should be ignored.

---

-Additionally if possible

If I did the search for “yellow gold blue diamond band“

I only want to pull the following tags:

• yellow gold
• band
• blue diamond

the diamond tag would be ignored because the blue diamond tag would be the match.

---

How can I do this?
