Subject [jira] [Created] (LUCENE-4419) Test RecursivePrefixTree indexing non-point data
Date Sun, 23 Sep 2012 20:22:07 GMT
David Smiley created LUCENE-4419:

             Summary: Test RecursivePrefixTree indexing non-point data
                 Key: LUCENE-4419
             Project: Lucene - Core
          Issue Type: Improvement
          Components: modules/spatial
            Reporter: David Smiley

RecursivePrefixTreeFilter was modified in ~July 2011 to support spatial filtering of non-point
indexed shapes.  It seems to work when playing with the capability but it isn't tested.  It
really needs to be as this is a major feature.

I imagine an approach in which some randomly generated rectangles are indexed and then a randomly
generated rectangle is queried.  The right answer can be calculated brute-force and then compared
with the filter.  In order to deal with shape imprecision, the randomly generated shapes could
be generated to fit a course grid (e.g. round everything to a 1 degree interval).
