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'.<?phprenderCode("<?phpclassArticle{publicfunctionsetTableDefinition(){\$this->hasColumn('name','string');\$this->hasColumn('content','string');\$this->index('content',array('fields'=>'content','type'=>'fulltext'));}}?>");
