Hi. There's some kinda mismatch between docs and function_definition.php file for ezfind module.

Doc file tells about parameters for search function at 6.2.1 (page 11). it says that query is not required, but function_definition.php say that it is.

I think that documentation should to be change.

Steps to reproduce

just check
http://svn.ez.no/svn/extensions/ezfind/ezp4/trunk/extension/ezfind/modules/ezfind/function_definition.php

 'parameters' => array( array( 'name' => 'query',
                                                               'type' => 'string',
                                                               'required' => true,
                                                               'default' => '' ),

and http://svn.ez.no/svn/extensions/ezfind/ezp4/trunk/extension/ezfind/doc/ezfind_2.0_manual.odt at the bottom of page 11.
