Try:
http://www.mysite.com/search?path.query:record=magazine&path.level:record:int=-1

Using a hidden field in the form with the name set to "path.level:record:int" 
and the value set to -1 should do it.  This marshalls a path variable as 
something like a dict (a record object), and stores the integer '-1' as the 
value for the key 'level'.
