I am trying to execute below query against Solr
q=cancer care facilities
&debugQuery=true
&defType=edismax
&bf=query({!lucene df=article q.op=AND v=$q},0)
but it throws below error after execution,
org.apache.solr.common.SolrException: undefined field: "v"

But when we try same thing with Parameter dereferencing for bf then it works
as expected,
q=cancer care facilities
&debugQuery=true
&defType=edismax
&bf=$my_func
&my_func=query({!lucene df=article q.op=AND v=$q},0)
What can be a reason for this? How can we pass function directly as a bf
parameter ?
