Remove Infinity values for Range facets when no docs match the range

[dadoonet]

Hi,

As discussed in the mailing list : http://groups.google.com/group/elasticsearch/browse_thread/thread/560c9b8954668931/d7b932e895bd7d4b

Just wondering if we must keep Infinity or not but just changing

in https://github.com/elasticsearch/elasticsearch/blob/master/modules/elasticsearch/src/main/java/org/elasticsearch/search/facet/range/RangeFacet.java#L60

        double min = Double.POSITIVE_INFINITY;
        double max = Double.NEGATIVE_INFINITY;

to

        double min = Double.NEGATIVE_INFINITY;
        double max = Double.POSITIVE_INFINITY;

That change won't help, you will simply see other "infinity values". In general, it can simply not output the min/max values if the count is 0.
