As detailed in previous email, "termfreq" is not a "field" - it is a
"transformer" or function. Technically, it is actually a "ValueSource".
If you look at the TextResponseWriter.writeVal method you can see you it
kicks off the execution of transformers for writing documents.

Subject: Re: Doc's FunctionQuery result field in my custom SearchComponent
class ?
Eric ,
In freq:termfreq(product,'spider') , freq is alias for 'termfreq' function
query so I could have that field with name 'freq' in document response.
this is my code which I am using to get document object and there is no
termfreq field in its fields collection.
DocList docs = rb.getResults().docList;
DocIterator iterator = docs.iterator();
int sumFreq = 0;
String id = null;
for (int i = 0; i < docs.size(); i++) {
try {
int docId = iterator.nextDoc();
// Document doc = searcher.doc(docId, fieldSet);
Document doc = searcher.doc(docId);
Thanks,
Tony

Where are you getting the syntax
freq:termfreq(product,'spider')
? Try just
termfreq(product,'spider')
you'll get an element in the doc labeled 'termfreq', at least
I do.
