how to retrieve a doc from its docID ?

[Giovanni Gherdovich]

Hi all,

when querying my solr instance, the answers I get
are the document IDs of my docs. Here is how one of my docs
looks like:

-- -- >8 -- -- >8 -- -- >8 -- -- >8 -- -- >8 -- --
<add>
    <doc>
        <field name="text">hello solar!</field>
        <field name="id">123</field>
    </doc>
</add>
-- -- >8 -- -- >8 -- -- >8 -- -- >8 -- -- >8 -- --

here is the response if I query for "solar" :

-- -- >8 -- -- >8 -- -- >8 -- -- >8 -- -- >8 -- --
<response>
    <lst name="responseHeader"></lst>
    <result name="response" numFound="1" start="0" maxScore="1.0">
        <doc><float name="score">1.0</float>
        <str name="id">123</str></doc>
    </result>
</response>
-- -- >8 -- -- >8 -- -- >8 -- -- >8 -- -- >8 -- --

which is, solr gives me the doc ID. How to retrieve the doc's field "text"
given its id ?

cheers,
Giovanni
