Looking at the example here: http://wiki.apache.org/solr/SimpleFacetParameters#head-4ba81c89b265c3b5992e3292718a0d100f7251ef
This being the query for selecting PDF:q=mainquery&fq=status:public&fq={! tag=dt}doctype:pdf&facet=on&facet.field={!ex=dt}doctype
How would you do the query for selecting PDF OR Excel AND, assuming there is another facet field named author, where author is Mike?
Thank you, Nasseam
