Search.tml

<html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd">
    <body>

    <t:form>

        <t:errors>

        <t:label for="search"/>
        <t:textfield t:id="search"/>

        <input type="submit" value="Search"/>

    </t:form>

    </body>
</html>

The Errors component here will display any validation errors that occur when the form is submitted.
