nknize opened a new pull request, #1017: URL: https://github.com/apache/lucene/pull/1017
Adds new doc value field to support LatLonShape and XYShape doc values. The implementation is inspired by ComponentTree. A binary tree of tessellated components (point, line, or triangle) is created. This tree is then DFS serialized to a variable compressed DataOutput buffer to keep the doc value format as compact as possible. DocValue queries are performed on the serialized tree using a similar component relation logic as found in SpatialQuery for BKD indexed shapes. To make this possible some of the relation logic is refactored to make it accessible to the doc value query counterpart. Current limitations (to be addressed in follow up PR) 1. Only Polygon Doc Values are tested 2. CONTAINS relation not yet supported 3. Only BoundingBox queries are supported (General Geometry Queries will be added in a follow on enhancement PR) -- This is an automated message from the Apache Git Service.
