David Smiley updated SOLR-10039: -------------------------------- Attachment: SOLR_10039_LatLonPointSpatialField.patch The attached patch has most everything but it's not quite committable. I'm internally using a 6.4 based branch so the diff includes stuff that won't be needed for trunk or 6.5+. The field extends {{AbstractSpatialFieldType}} and thus inherits the functionality and integration with the rest of Solr spatial. The main TODOs are: * make indexed & docValues attributes configurable * integrate Polygon support. I would have liked to have introduced this embedded {{SpatialStrategy}} implementation to Lucene spatial-extras but I didn't think depending on sandbox was a good idea, at least not now, so I opted not to. > LatLonPointSpatialField > ----------------------- > > Key: SOLR-10039 > URL: https://issues.apache.org/jira/browse/SOLR-10039 > Project: Solr > Issue Type: New Feature > Security Level: Public(Default Security Level. Issues are Public) > Components: spatial > Reporter: David Smiley > Assignee: David Smiley > Attachments: SOLR_10039_LatLonPointSpatialField.patch > > > The fastest and most efficient spatial field for point data in Lucene/Solr is > {{LatLonPoint}} in Lucene's sandbox module. I'll include > {{LatLonDocValuesField}} with this even though it's a separate class. > LatLonPoint is based on the Points API, using a BKD index. It's multi-valued > capable. LatLonDocValuesField is based on sorted numeric DocValues, and thus > is also multi-valued capable (a big deal as the existing Solr ones either > aren't or do poorly at it). Note that this feature is limited to a > latitude/longitude spherical world model. And furthermore the precision is > at about a centimeter -- less precise than the other spatial fields but > nonetheless plenty good for most applications. Last but not least, this > capability natively supports polygons, albeit those that don't wrap the > dateline or a pole. > I propose a {{LatLonPointSpatialField}} which uses this.
