Subject Re: question(s) re lucene spatial toolkit aka LSP aka spatial4j

Hey solr-user, are you by chance indexing LineStrings?  That is something I
never tried with this spatial index.  Depending on which iteration of LSP
you are using, I figure you'd either end up indexing a vast number of points
along the line which would be slow to index and make the index quite big, or
you might end up with a geohash granularity that will look more like a very
blocky (i.e. pixelated) approximation of the line that is much courser and
will thus trigger searches "near" the line to match the line.  I don't have
this use-case in my work so I haven't put that much thought into handling
lines -- I just do points & polygons & circles & rects.
