passedArgs should be data or parsedData in the documentations

[ghost]

I think

$this->Article->parseCriteria($this->passedArgs);

should be

$this->Article->parseCriteria($this->data['Article']);

or

$this->Article->parseCriteria($this->parsedData['Article']);

in README and the documentation at http://cakedc.com/downloads/view/cakephp_search_plugin.

Check the bottom of the README, what you're looking for is explained there:

commonProcess method defined in Prg component allow you to inject search in any index controller with just 1-2 lines of additional code.
You should pass model name that used for search. By default it is default Controller::modelClass model.

If there still issues or questions just ask.

I occurred the same problem concerning this issue.

In this case, the sample code of controller class defines "array('field' => 'status', 'type' => 'checkbox'),".

The sample code doesn't work when the status check box was selected multiple values.
(The SQL code will be generated like "WHERE Article.status = (1|2)" and returns incorrect result.)

To solve this problem, I specified argument "$this->data['Article']" to parseCriteria.

I think it was very complicated to understand how it works.

Any right ways to do this?
