function ext_search_node_ref_potential_references in Extended search page 7

Fetch an array of all candidate referenced nodes.

Parameters

$page: The page object.

$instance: The field instance.

$string: Optional string to filter titles on (used by autocomplete).

$limit: If non-zero, limit the size of the result set.

Return value

An array of valid nodes in the form: array( nid => array( 'title' => The node title, 'rendered' => The text to display in widgets (can be HTML) ), ... ) @todo Check whether we still need the 'rendered' value (hook_options_list() does not need it anymore). Should probably be clearer after the 'Views' mode is ported.
