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

Thu Jul 23 04:19:04 UTC 2015

Hi Filip:

For debugging purposes, my suggestion is to check the solr log directly
since it is much easier to read. The log is located at
http://YOUR-SERVER-IP/solr/#/~logging.

Not sure what caused your problem, but I just finished a CKAN 2.3 + Solr
5.1.0 + ckanext-spatial with solr-spatial-field backend installation on a
Ubuntu 14.04 machine. Both indexing and searching (point, bbox and polygon)
have worked well so far.

The following links are some installation notes:

1. Install Solr 5 for CKAN 2.3:
https://gist.github.com/u10313335/1cd42194992c501fe5c6
2. ckanext-spatial w/ solr-spatial-field backend
https://gist.github.com/u10313335/5649488bc3a4037e1357

(Note: I did not use the latest 5.2.1 version because it may fail when
restarting. For details, see https://github.com/ckan/ckan/issues/2524.)

Hope that helps.

Cheers,

Sol
