How to parse other modules tag in my module tag

Hello, I have a problem with parsing other modules tag in my module tag.

{exp:name:method parse="inward"}
    {super_search_keywords}
{/exp:name:method}

or

{exp:name:method string="{super_search_keywords}" parse="inward"}

How you can see I did use two ways of input, and attribute parse. but still it is not working. I want to parse tag and have his value. And what I only get is tag.
