Here's one source of documentation for it. 

Simply bind parameters in pages.xml to values in the backing component to get a 2 way passing of values from the form to the backing bean via request parameters.

i.e. 


  | <page view-id="mySearch">
  | <param name="lastName" value="#{myBean.lastName}">
  | </page>
  | 

Now, when you call \mySearch.seam?lastName=smith the value will be put into the backing bean.

On your form, you simply put : 


  |   <h:inputText value="#{myBean.lastName}"/>
  | 

and the parameter will appear in the form based on the parameter.

So the parameter makes the trip from  parameter in the request-> Put into the backing bean -> Value on the form bound to the backing bean.

When you run the query, you can just refer to the lastName field in the MyBean class to get the value.
