Another stumbling block... I want to be able to return those lat,lng values within the current map viewport/window. This relates to http://wiki.apache.org/solr/SolrAdaptersForLuceneSpatial4#Sorting_and_Relevancy, here it states "A common spatial requirement is to sort the search results by distance from a point such as the center of a map window". My requirement is just to return the results within the map window, although not by imposing a query constraint, it is kind of like having a facet query as a facet limit. In fact for performance reasons I don't mind receiving some results outside the map window.
My thought is that the most efficient way is to calculate the 1 to 4 geohash prefix tree grids which minimally encompass the map window. Then somehow limit the results to being contained within these grids. So does that make sense? I presume there is no straightforward way of doing this (prefix query maybe?) without coding some solution. -- View this message in context: http://lucene.472066.n3.nabble.com/Using-GeohashPrefixTree-for-map-clustering-tp4026819p4027937.html Sent from the Lucene - Java Users mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
