what is the use of apex:param tag in Visual Force

<apex:outputLink value="http://google.com/search">

    Search Google

    <apex:param name="q" value="{!contact.name}"/>


If i click Preview in Visual Force page it is simply linked to contacts page,how the tag is working?please explain with example


So the name & value attribute of <apex:param will form a key value pair parameter appended to the URL. See the below example, which represents with param and without param. The name attribute q and value attribute account.name forms the ?q={!account.name} appended to the URL.
