manual/docs/Getting started - Indexes - Adding indexes.php

+<?php ?>
+You can add indexes by simple calling Doctrine_Record::option('index', $definition) where $definition is the 
+definition array. The structure of the definition array is as follows:
+<div class='sql'>
+<pre>
+[   indexName1 => [col1 => [col1-options], ... , colN => [colN-options]
+    indexName2 => ...
+    indexNameN => ]
+</pre>
+</div>
+<br \><br \>
+An example of adding a simple index to field called 'name':
+<br \><br \>
+<?php
+renderCode("<?php
+class IndexTest extends Doctrine_Record
+{
+    public function setTableDefinition()
+    {
+        \$this->hasColumn('name', 'string');
+    }
+    public function setUp()
+    {
+        \$this->option('index', array('myindex' => 'name'));
+    }
+}
+?>");
+?>
+<br \><br \>
+An example of adding a multi-column index to field called 'name':
+<br \><br \>
+<?php
+renderCode("<?php
+class MultiColumnIndexTest extends Doctrine_Record
+{
+    public function setTableDefinition() 
+    {
+        \$this->hasColumn('name', 'string');
+        \$this->hasColumn('code', 'string');
+    }
+    public function setUp()
+    {
+        \$this->option('index', array('myindex' => array('name', 'code')));
+    }
+}
+?>");
+?>
+<br \><br \>
+An example of adding a multiple indexes on same table:
+<br \><br \>
+<?php
+renderCode("<?php
+class MultipleIndexTest extends Doctrine_Record
+{
+    public function setTableDefinition() 
+    {
+        \$this->hasColumn('name', 'string');
+        \$this->hasColumn('code', 'string');
+        \$this->hasColumn('age', 'integer');
+    }
+    public function setUp()
+    {
+        \$this->option('index', 
+                      array('myindex' => array('name', 'code')
+                            'ageindex' => 'age')
+                            );
+    }
+}
+?>");
+?>

manual/docs/Getting started - Indexes - Index options.php

+<?php ?>
+Doctrine offers many index options, some of them being db-specific. Here is a full list of availible options:
+<div class='sql'>
+<pre>
+unique      => boolean(true / false)        
+        whether or not the index is unique index
+
+sorting     => string('ASC' / 'DESC')      
+        what kind of sorting does the index use (ascending / descending)
+
+primary     => boolean(true / false)        
+        whether or not the index is primary index
+
+fulltext    => boolean(true / false)        
+        whether or not the specified index is a FULLTEXT index (only availible on Mysql)
+        
+gist        => boolean(true / false)        
+        whether or not the specified index is a GiST index (only availible on Pgsql)
+</pre>
+</div>

manual/docs/Getting started - Indexes - Special indexes.php

+<?php ?>
+Doctrine supports many special indexes. These include Mysql FULLTEXT and Pgsql GiST indexes.
+In the following example we define a Mysql FULLTEXT index for the field 'content'.
+<br \><br \>
+<?php 
+renderCode("<?php
+class Article 
+{
+    public function setTableDefinition() 
+    {
+    	\$this->hasColumn('name', 'string');
+        \$this->hasColumn('content', 'string');
+    }
+    public function setUp() 
+    {
+        \$this->option('index', 
+                        array('content' =>
+                            array('content' => 
+                                array('fulltext' => true));
+    }
+}
+?>");
