Filtering out documents (greater selectivity) seems like it should be the primary goal. But perhaps the problem could be parameterized? What if you gave a minimum tile size that you wanted to use? Then there would be only one correct answer I believe? So the problem would essentially be boiled down to this: - find the minimum area that still encompasses the entire circle - minimize the number of tiles - don't use tiles smaller than minTile That minTile param allows you to trade off between filtering accuracy and faster tile filtering. Without the param (or until it can be implemented) the correct approach seems like the above, without a minTile. This sounds to me like the old approach is correct. -Yonik Apache Lucene Eurocon 2010 18-21 May 2010 | Prague --------------------------------------------------------------------- To unsubscribe, e-mail: java-dev-unsubscr...@lucene.apache.org For additional commands, e-mail: java-dev-h...@lucene.apache.org
