Function Queries

[outre <sp...@hotmail.com>]

Hi,

I was wondering if function queries are supported in SOLR1.3?

I looked thru http://wiki.apache.org/solr/FunctionQuery, and tried to run an
example on my SOLR setup. It doesn't seem though that _val_ hook has any
effect on sorting, and "score" parameter doesn't seem to return computed
values.

In my index I have fields "price" (double) and "store"(string), and just for
the sake of an example all I am doing is multiplying the price by 2. So my
query looks like this:
q=store:"adidas"&_val_:"product(price,2)"&fl=store,price,score

Based on wiki, I'd expect to see doubled price in the score field, but I
seem to be getting SOLR document scores. Am I misunderstanding something
here?

Thanks

Just to confirm. The query works if written as in Yonik's comment. 

Thanks

_val_ is a magic field name for the lucene/solr query parser.
So try something with _val_ in the query string:
q=_val_:"product(price,2)"
