Select multiple facets with OR instead of AND

[Dhanushka Samarakoon]

Hi All,

I'm running the following query.

http://localhost:8983/solr/select/?q=green&version=2.2&indent=on&qt=dismax&;
fq=fKeyword:"NITROGEN"&fq=fKeyword:"corn"
&facet=on&facet.mincount=1&facet.field=fKeyword

What this returns me is a set of results which has both the keywords
in fKeyword. Instead I need all the records that has at least one of them as
a keyword.
Any suggestions?

Thanks.
