You can use the termfreq or tf function query in your field list to return
the term frequency for a term, like:
fl=id,tf(foods,'pizza')

Subject: get term frequency, just only keywords search
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
