> Hi [~dsmiley],
> I have been working on a prefix tree based on goggle S2 geometry 
> (https://s2geometry.io/) to be used mainly with Geo3d shapes with very 
> promising results, in particular for complex shapes (e.g polygons). Using 
> this pixelization scheme reduces the size of the index, improves the 
> performance of the queries and reduces the loading time for non-point shapes. 
> If you are ok with this contribution and before providing any code I would 
> like to understand what is the correct/prefered approach:
> 1) Add new depency to the S2 library 
> (https://mvnrepository.com/artifact/io.sgr/s2-geometry-library-java). It has 
> Apache 2.0 license so it should be ok.
> 2) Create a utility class with all methods necessary to navigate the S2 tree 
> and create shapes from S2 cells (basically port what we need from the library 
> into Lucene).
> What do you think?
