    <p>We have a simple search on our site that uses MySQL fulltext search and for some reason it doesn't seem to be returning the correct results. I don't know if it's some kind of issue with Amazon RDS (where our database server resides) or with the query we are requesting. </p> <p>Here is the structure of the database table:</p> <pre><code>CREATE TABLE `items` ( `object_id` int(9) unsigned NOT NULL DEFAULT '0', `slug` varchar(100) DEFAULT NULL, `name` varchar(100) DEFAULT NULL, PRIMARY KEY (`object_id`), FULLTEXT KEY `name` (`name`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1; </code></pre> <p>And here is a simple fulltext search query on this table and the returned results:</p> <pre><code>select object_id ,slug,name from items where MATCH (name) AGAINST ('+ski*' IN BOOLEAN MODE) order by name; +-----------+-----------------------------------+------------------+ | object_id | slug | name | +-----------+-----------------------------------+------------------+ | 10146041 | us/new-hampshire/dartmouth-skiway | Dartmouth Skiway | +-----------+-----------------------------------+------------------+ </code></pre> <p>If I instead use LIKE I get a different set of results:</p> <pre><code>select object_id,slug,name from items where name LIKE "%ski%" order by name; +-----------+------------------------------------------+----------------------------------+ | object_id | slug | name | +-----------+------------------------------------------+----------------------------------+ | 10146546 | us/new-york/brantling-ski | Brantling Ski | | 10146548 | us/new-york/buffalo-ski-club | Buffalo Ski Club | | 10146041 | us/new-hampshire/dartmouth-skiway | Dartmouth Skiway | | 10146352 | us/montana/discover-ski | Discover Ski | | 10144882 | us/california/donner-ski-ranch | Donner Ski Ranch | | 10146970 | us/new-york/hickory-ski-center | Hickory Ski Center | | 10146973 | us/new-york/holimont-ski-area | Holimont Ski Area | | 10146283 | us/minnesota/hyland-ski | Hyland Ski | | 10145911 | us/nevada/las-vegas-ski-snowboard-resort | Las Vegas Ski &amp; Snowboard Resort | | 10146977 | us/new-york/maple-ski-ridge | Maple Ski Ridge | | 10146774 | us/oregon/mount-hood-ski-bowl | Mt.

I'm hoping that some MySQL expert out there can point out the error in our query.</p> <p>Thanks in advance for your help!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
