    <blockquote> <p>How can I modify MySQL to accommodate this?</p> </blockquote> <p>You'll have to change MySQL's idea of what a word is.</p> <p>Firstly, the default minimum word length is 4. This means that no search term containing only words of &lt;4 letters will ever match, whether that's ‘C++’ or ‘cpp’. You can configure this using the <a href="http://dev.mysql.com/doc/refman/5.1/en/server-system-variables.html#sysvar_ft_min_word_len" rel="noreferrer">ft_min_word_len</a> config option, eg. in your my.cfg:</p> <pre><code>[mysqld] ft_min_word_len=3 </code></pre> <p>(Then stop/start MySQLd and rebuild fulltext indices.)</p> <p>Secondly, ‘+’ is not considered a letter by MySQL. You can make it a letter, but then that means you won't be able to search for the word ‘fish’ in the string ‘fish+chips’, so some care is required. And it's not trivial: it requires recompiling MySQL or hacking an existing character set. See the section beginning “If you want to change the set of characters that are considered word characters...” in <a href="http://dev.mysql.com/doc/refman/5.1/en/fulltext-fine-tuning.html" rel="noreferrer">section 11.8.6</a> of the doc.</p> <blockquote> <p>escape the + character during the process of entering my data as something like "__plus" and then modifying my search to accomodate</p> </blockquote> <p>Yes, something like that is a common solution: you can keep your ‘real’ data (without the escaping) in a primary, definitive table — usually using InnoDB for ACID compliance. Then an auxiliary MyISAM table can be added, containing only the mangled words for fulltext search bait. You can also do a limited form of stemming using this approach.</p> <p>Another possibility is to detect searches that MySQL can't do, such as those with only short words, or unusual characters, and fall back to a simple-but-slow LIKE or REGEXP search for those searches only. In this case you will probably also want to remove the stoplist by setting <a href="http://dev.mysql.com/doc/refman/5.1/en/server-system-variables.html#sysvar_ft_stopword_file" rel="noreferrer">ft_stopword_file</a> to an empty string, since it's not practical to pick up everything in that as special too.</p>

    1. CO@bobince: (Re the discussion in the comments above, thank you for answering this easily-understandable question in a clear manner.) Out of curiosity, how would you do stemming with this approach? Replace every word in the auxiliary table with its stem?

    2. COEssentially yes (processing the words in search queries in the same way of course). Typically you'd use an existing suffix-stripping stemmer library for your preferred languages. (For both values of ‘language’; see eg. Porter's algorithm for English in many programming languages.)

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.
