MitchK, I need a range filter, not a token filter. I'm trying to filter on ranges. If you have code, I'd love to see it.
Israel, I've been using the JTeam spatial plugin as a model for my work. I initially tried to use the plugin, but there were some serious bugs in the code. I was able to make some changes based on the Lucene spatial code, but other problems popped up. I tried replacing the cartesian filter with a bounding box using simple latitudes and longitudes by using a ChainedFilter with 2 numeric range filters and then passing it in to a lat/long distance filter, but neither seemed to work out of the box. It's as if I need to override the default getDocIdSet methods in order to actually get a result. Is there a need to override that method? On would think they should work as-is. Thank you both for your help.
