indexed and stored fields don't appear in the response

[Sandy Ding]

Part of my schema is as follows:

    <field name="_version_" type="long" indexed="true" stored="true"/>
    <field name="id" type="mem_long" indexed="true" stored="true"
required="true" multiValued="false" docValues="true" />
     <field name="bizid" type="string" indexed="true" stored="false"
required="false" multiValued="true" docValues="true"/>

When I issue the following command,

    curl "http://localhost:8983/solr/pa_info/select?q=*:*&rows=10";

The response is:

<response>
