FAcet with " " values are displayes in output

[Prasi S]

Hi ,
Im using solr 4.4 for our search. When i query for a keyword, it returns
empty valued facets in the response

<lst name="facet_counts">
<lst name="facet_queries"/>
<lst name="facet_fields">
<lst name="Country">
*<int name="">1</int>*
<int name="USA">1</int>
</lst>
</lst>
<lst name="facet_dates"/>
<lst name="facet_ranges"/>
</lst>

I have also tried using facet.missing parameter., but no change. How can we
handle this.


Thanks,
Prasi
