Hi Mark,
I asked a follow-up question/observation to your Stackoverflow
instantiation of your question.
I also wrote the following, which doesn’t yet fit into an answer because I
don’t know what problem you are yet experiencing:
Some technical details: geo=true|false is an attribute on the field type;
it isn't a request parameter. Should you want to change it to geo=false,
you will also have to set the worldBounds and certainly re-index. Almost
any change to a field type in the schema requires a re-index. If your
units stay degrees then you can continue to use "lat,lon" format, but if
you use another unit specific to some projection then it's not degrees and
I suggest switching to "x y" to avoid confusion with lat,lon format. FYI
units=degrees is required but it has no effect. When geo=true, the 'd' in
geofilt is kilometers, when geo=false, 'd' is in the units of the numbers
you put into the index. The docs are here:
https://cwiki.apache.org/confluence/display/solr/Spatial+Search
It would be awesome if you want to help further spatial in Lucene/Solr.
This year is looking like a great year for spatial — I’m particularly
excited about a new “FlexPrefixTree” from Varun (GSOC 2014) together with
the latest advances in auto-prefixing to be released in Lucene/Solr 5.0.
