The example docs we distribute have a bunch of stores that have the exact same location. That lead to some head scratching about why changing the distance in the example queries seemed to make no difference in the number of returned results then all of a sudden it reduced the number of hits drastically.
Any objections to a patch that adds an arbitrary distance (say 1/4 mile or so) to all of the stores in the example docs that have the same location? If not, I'll put up a JIRA and attach a patch. Erick
