SOLR Interface

Use Cases

As an admin of a CKAN instance I want to have the facility to use SOLR, both alongside and as a replacement for the existing full text search in CKAN.

Design

There are two main options for getting data into SOLR:

• POST the records to SOLR in XML format (​docs)
• Direct connection Setup SOLR (​docs)
  • Provide SELECT statements to do queries
  • Process is initiated by doing a GET to a particular SOLR URL

The preference is for the first option as the abstraction provides more flexibility in the db and more control about what gets indexed.

Tickets

• Get a SOLR instance running locally and/or eu1, using basic config.
• Harness one of the three python SOLR libraries to send SOLR Update XML of CKAN Packages.
• Write tests for SOLR by sending data with SOLR library and using JSON interface for queries.
• Optimise the SOLR settings for searching our data well - fields description in schema.xml. (Link to schema.xml in developer docs.)
• Provide option to connect CKAN's search WUI to SOLR back-end.
