Can Lucene index the openstreetmap.org (OSM) node db (400M
latitude/longitude pairs), and then find the 20 nodes closest to a
given latitude/longitude?
More specifically:
% Can Lucene index numerical data and understand that 16 is close to
15, but far away from 160000?
% Is Lucene reasonably fast indexing 400M floating point pairs?
% After Lucene creates the 400M index, can it return search results
reasonably fast?
% Is there a guide/tutorial that shows how to use Lucene to index
numerical data (I'm using Plucene, but I'll settle for any sort of
guide)?
I tried to index OSM data w/ SQLite3, but it took forever.
I realize I could use MySQL/PostgreSQL, but I'm looking for an
embedded/serverless solution.
