[ckan-dev] Updating Solr to support point search and confusion with Spatial Search Widget

Wed Jul 22 15:11:03 UTC 2015

Hi all,

So, another update: Instead of updating search index with
solr-spatial-field backend in development.ini, I have first done an update
with solr backend and then another search index update with
solr-spatial-field. The search index was updated without errors, all
datasets are listed in search, and adding points/polygons to spatial
attribute in dataset does not generate any errors.

However, the spatial search widget still does not show any results when
performing search (with solr-spatial-field configuration). Did anyone have
the same problem? Does spatial search work in your case?

Cheers
