(Current release versions (beta4 and beyond) contain updates to work with current (2015) Search API and Search API Solr)

Sarnia allows a Drupal site to interact with and display data from Solr cores with arbitrary (non-Drupal) schemas, mainly by building Views. This is useful for Solr cores that index large, external (non-Drupal) datasets that are either not practical to store in Drupal or may already be indexed in Solr.

Sarnia treats records from Solr as Drupal entities, although listing, filtering, and displaying Sarnia entities should be done using Views. Solr properties can be formatted within Views fields using field formatters (hook_field_formatter_info(), hook_field_formatter_view()).

There is user documentation with screenshots in the handbook.

This module depends on Search API, Search API Solr, and Views.

Latest development

  • After a prolonged period, the current release version has been patched and tested to work with the latest Search API and Search API Solr. The included documentation has been updated.
  • There is now working FacetAPI integration (requires search_api_facetapi, which is included in the Search API project)
  • Date facets are supported on fields declared as solr.TrieDateField ("tdate"). It may be necessary (depending on the version of Solr) to force disabling of fulltext search on fields declared as solr.TrieDateField, by setting rules in the "Fulltext search" section on the "Solr Schema" tab of a Sarnia Server configuration item. See comment #9 in issue #2513444: Support for date fields/facets.
  • A patch was originally made where Sarnia handled filter testing for NULL values. This has now been removed in favor of allowing Search API to handle NULL testing. In limited cases, it may be necessary to review pre-existing Views. See #2496751: Delete SarniaViewsHandlerFilter::operator_options() and #1318904: Improved handling for NULL values in Views.
  • Random sorts in Views can be added by applying a patch to Search API described in #1197538: Random sort in Views. The Sarnia project contains example drush makefile code that applies this patch.

This module was developed by Palantir.net, and sponsored by the Field Museum of Natural History. Development supported by OpenPlus and currently Askari Solutions Inc.
