get term frequency, just only keywords search

[danielitos85]

I need to get the TermFrequency in Solr4 but just about my keywords search
and not for all the keywords that a field cointains.

I try to explain with an example:

I have this fiels:

<field name="id"            type="string"     indexed="true"   
stored="true"    required="true" /> 
<field name="foods"         type="text"       indexed="true"   
stored="true"    required="true"        termVectors="true" 
termPositions="true"    termOffsets="true"/> 

when I try to searh into field "foods" the keyword "pizza" like this:

http://localhost:8983/solr/mycore/select?q=pizza&fl=id&tv=true&df=foods&tv.tf_idf=true&tv.tf=true&tv.df=true&tv.fl=foods&omitHeader=true&defType=dismax

this is my results:

<response>
<result name="response" numFound="1" start="0">
    <doc>
        <str name="id">1</str>
    </doc>
</result>
<lst name="termVectors">
    <str name="uniqueKeyFieldName">id</str>
    <lst name="1">
        <str name="uniqueKey">1</str>
        <lst name="foods">
            <lst name="pizza">
                <int name="tf">5</int>
                <int name="df">3</int>
                <double name="tf-idf">1.6666666666666667</double>
            </lst>
            <lst name="ice-cream">
                <int name="tf">2</int>
                <int name="df">3</int>
                <double name="tf-idf">0.6666666666666666</double>
            </lst>
            <lst name="tomato">
                <int name="tf">2</int>
                <int name="df">1</int>
                <double name="tf-idf">2.0</double>
            </lst>
        </lst>
    </lst>
</lst>

Now, my question is: why I get the tf for all the indexed keywords into
field foods and not only for my keyword search ("pizza")?

Please, have you any suggests? Thanks in advance
