What I understand is the following: Your goal is to restrict documents search results to spatial extends similar to the syntax which restricts documents based on their (creation/modification) date within a given time period. For the indexing field descriptions are added to the indexer in order to tell him, which fields to index and which store. You now want to add a new type, let's call it coordinates (WGS84) as a new field type to index. For Lucene API users nothing changes from here on for the index. Now, in a search, a bounding box is given as two WGS84 coordinates (= lat/lon numbers north/west and lat/lon numbers south east) being a syntax extension. Based on the location value (if any) of each hit a result set comes out which is a subset of all hits if there was no spatial filter (don't now how you handle hits which have no lat/lon location value?). Is that right? Now what are only asking for? The most performant strategy?
