Use function in condition

[nabil Kouici]

Hi,
Is it possible to use functions (function query 
https://cwiki.apache.org/confluence/display/solr/Function+Queries) in q or fq 
parameters to build a complex search expression. 
For exemple, take only documents that sum(field1,field2)> 100. Another exemple: 
if(test,value1,value2):vallue3
Regards,Nabil.
