Subject [jira] [Commented] (SOLR-10038) Spatial Intersect Very Slow For Large Polygon and Large Index
Date Wed, 01 Feb 2017 17:05:52 GMT

    [ https://issues.apache.org/jira/browse/SOLR-10038?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15848635#comment-15848635

-------------------------------------

David, thank you for the last answer. It is clear now. 

I observed that for very large multipolygon (10MB) the query never finishes, but when I split
the multipolygon into many polygons and issue a query for each polygon, it is really fast.

Does solr support  very large multipolygon as query parameter? Does it internally split the
mulipolygon into polygons?

Could you clarify this point?

> 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?
