You can add indexes by simple calling Doctrine_Record::index('indexName', $definition) where $definition is the definition array.

An example of adding a simple index to field called 'name':

hasColumn('name', 'string'); \$this->index('myindex', array('fields' => 'name'); } } ?>"); ?>

An example of adding a multi-column index to field called 'name':

hasColumn('name', 'string'); \$this->hasColumn('code', 'string'); \$this->index('myindex', array('fields' => array('name', 'code'))); } } ?>"); ?>

An example of adding a multiple indexes on same table:

hasColumn('name', 'string'); \$this->hasColumn('code', 'string'); \$this->hasColumn('age', 'integer'); \$this->index('myindex', array('fields' => array('name', 'code'))); \$this->index('ageindex', array('fields' => array('age')); } } ?>"); ?>
