    <p>My proposal is the following:</p> <p>Let's say the user input is: <code>ab*</code> where <code>*</code> is the wildcard. Count all the known letters and the wildcards and create an array where element 0 is the number of wildcards and every other element key is a known letter with a value the number of times it is given in the user input:</p> <pre><code>function GetArrayLetters($userInput) { ... // produces something like $letters = ( 0 =&gt; 1, 'a' =&gt; 1, 'b' =&gt; 1); return $letters; } </code></pre> <p>Using that array modify your query by adding the number of wildcards in each letter and at the word's length:</p> <pre><code># with only one wildcard, the query will become: SELECT * FROM scrabble WHERE a &lt;= 2 AND b &lt;= 2 AND c &lt;= 1 .... ... AND length &lt;= 3 </code></pre> <p>Now put the results somewhere (an array) and examine each word in turn. Go through each letter and subtract one for each known letter from your $letters array; If the value of a known letter is zero, subtract from element 0 instead (the wildcard). If you get a negative value for the wildcard, then discard the word:</p> <pre><code>foreach ($result_set AS $word) { $letters = GetArrayLetters($userInput); for ($i = 0; $i &lt; str_len($word); $i++) { $letter = substr($word, $i, 1); if ( array_key_exists( $letter, $letters )) { if ($letters[$letter]) &gt; 0 { $letters[$letter] -= 1; } else { $letters[0] -= 1; // else subtract from the wildcard } } else { $letters[0] -= 1; } if ($letters[0] &lt; 0) { // if wildcard falls bellow zero, discard the word } } } </code></pre>

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.
