Re: Doc's FunctionQuery result field in my custom SearchComponent class ?

[Jack Krupansky]

Basically, the evaluation of function queries in the "fl" parameter occurs 
when the response writer is composing the document results. That's AFTER all 
of the search components are done.

SolrReturnFields.getTransformer() gets the DocTransformer, which is really a 
DocTransformers, and then a call to DocTransformers.transform() in each 
response writer will evaluate the embedded function queries and insert their 
values in the results as they are being written.

No sorry, I am still not getting the termfreq() field in my 'doc' object.
I do get the _version_ field in my 'doc' object which I think is
realValue=StoredField.

At which point termfreq() or any other FunctionQuery field becomes the part
of doc object in Solr ? And at that point can I perform some custom logic
and append the response ?

Thanks.

Hi,

I think the process of retrieving a stored field (through fl) is happens
after SearchComponent.

One solution: If you wrap a q params with function your score will be a
result of the function.
For example,

http://localhost:8080/solr/**collection2/demoendpoint?q=**
termfreq%28product,%27spider%**27%29&wt=xml&indent=true&fl=*,**score<http://localhost:8080/solr/collection2/demoendpoint?q=termfreq%28product,%27spider%27%29&wt=xml&indent=true&fl=*,score>


Now your score is going to be a result of termfreq(product,'spider')

Here is my code

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);

In doc object I can see the schema fields like 'id', 'type','format' 
etc.
but I cannot find the field 'freq' which I needed. Is there any way to
get
the FunctionQuery fields in doc object ?

Thanks,
Tony

 Hi,

I have extended Solr's SearchComonent class and I am iterating through
all the docs in ResponseBuilder in @overrider Process() method.

Here I want to get the value of FucntionQuery result but in Document
object I am only seeing the standard field of document not the
FucntionQuery result.

This is my query


http://localhost:8080/solr/**collection2/demoendpoint?q=**
spider&wt=xml&indent=true&fl=***,freq:termfreq%28product,%**
27spider%27%29<http://localhost:8080/solr/collection2/demoendpoint?q=spider&wt=xml&indent=true&fl=*,freq:termfreq%28product,%27spider%27%29>

Result of above query in browser shows me that 'freq' is part of <doc>
but its not there in Document object in my @overrider Process() method.

How can I get the value of FunctionQuery result in my custom
SearchComponent ?

Thanks,
Tony
