Summary: Overhaul Lucene spatial's distErrPct (was: Lucene spatial's
distErrPct is treated as a fraction, not a percent.)
Overhaul Lucene spatial's distErrPct
--
Key: LUCENE-4186
URL: https://issues.apache.org/jira/browse/LUCENE-4186
Project: Lucene - Core
Issue Type: Bug
Components: modules/spatial
Reporter: David Smiley
Assignee: David Smiley
Priority: Critical
Fix For: 4.0
Attachments: LUCENE-4186_distErrPct_upgrade.patch
The distance-error-percent of a query shape in Lucene spatial is, in a
nutshell, the percent of the shape's area that is an error epsilon when
considering search detail at its edges. The default is 2.5%, for reference.
However, as configured, it is read in as a fraction:
{code:xml}
fieldType name=location_2d_trie
class=solr.SpatialRecursivePrefixTreeFieldType
distErrPct=0.025 maxDetailDist=0.001 /
{code}

I updated the patch to add a
PrefixTreeStrategy.createIndexedFields(shape,distErr) specialization, and
accounted for the Spatial4j 0.3 update.
I plan to commit this sometime tomorrow.
