Subject [jira] [Commented] (SOLR-10038) Spatial Intersect Very Slow For Large Polygon and Large Index
Date Wed, 01 Feb 2017 16:23:51 GMT

    [ https://issues.apache.org/jira/browse/SOLR-10038?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15848578#comment-15848578
] 

David Smiley commented on SOLR-10038:
-------------------------------------

You're setting the levels explicitly but I don't recommend doing that -- set it in terms of
the largest distance you're willing to handle being the error (maxDistErr).  Both prefixTrees
will then determine which level to use that satisfies that requirement.

> Hi all, I have indexed the entire geonames points (lat/long) with JTS enabled, and I
am trying return all points (geonameids) within a certain polygon (e.g. Netherlands country
polygon). This query takes 3 minutes to return only 10.000  points. I am using only solr intersect.
no facets. no extra fitering.
> Is there any configuration that could slow down such a query to less than 300 ms?
