Hi,
Apologies if this isn't the list for geocouch questions.
Are there any plans to support map/reduce for geocouch queries?
In my use case, I am emitting geojson to OpenLayers. Currently I am
using javascript in the client to reformat the list of values into a
single FeatureCollection object.
{'type':'FeatureCollection', 'features':[ ...push rows[value] here... ]};
I did try just writing a map/reduce pair for the spatial member of
the design doc and hoped it would work, but it didn't work:
{"error":"{<<\"compilation_error\">>,\n<<\"Expression does not eval

I am using a "custom" version of geocouch... a git pull from August 19
(commit f764bcb61df8d00904c39611868db5a3a40f4178) merged with couchdb
1.0.1, plus a few minor tweaks to resolve conflicts (git is *so great*
for merging code)

Hi James,
this is the right place for GeoCouch questions.
You can't use map/reduce for spatial queries. You would need to make two
separate queries and merge them. Though there is something like a
multiview extension [1]. I haven't had the time to look into it yet, so
I'm not sure if it would solve you problems, but I've read that it has
GeoCouch support.
