Nga Chung commented on SDAP-110:
--------------------------------
This issue is related to https://issues.apache.org/jira/browse/SDAP-39 where we
found that providing a global POLYGON as a search parameter resulted in an
incorrect number of matches. Using a POLYGON with more points returns the
correct matches, but appears to perform worse than a bounding box query.
Perhaps we should index tiles as an ENVELOPE until we have non-retangular tiles.
> Unexpected results with tiles wider than 180 degrees

> Key: SDAP-110
> URL: https://issues.apache.org/jira/browse/SDAP-110
> Project: Apache Science Data Analytics Platform
> Issue Type: Bug
> Reporter: Frank Greguska
> Priority: Major
>
> Nexus needs to intelligently handle tiles that are wider than 180 degrees.
> Currently if a tile is ingested that is wider than 180 degrees the indexed
> shape is interpreted incorrectly resulting in missed searches.
> For example, if you create a Solr document that spans the longitude range:
> curl -X POST \
>
> 'http://127.0.0.1:8983/solr/nexustiles/update?_=1528823301125&boost=1.0&commitWithin=1000&overwrite=true&wt=json'
