Nested Function Query Syntax

[Rodrigo Rezende]

Hello,

I am trying to use function nested query syntax with solr 1.4.1, but I
am not sure if I am doing in right way:

I try this query and I get all documents which score is 12

http://localhost:8983/solr/articles.0/select/?q={!func}product(3,4)&fl=Document.title,score,&debugQuery=on

Using the same syntax, for nested query, I get an error

http://localhost:8983/solr/articles.0/select/?q={!func}query(hello)&fl=Document.title,score,&debugQuery=on

org.apache.lucene.queryParser.ParseException: Nested function query
must use $param or {!v=value} forms. got 'query(hello)'

Thanks,

Rodrigo.
