Islandora Solr provides a highly configurable interface to perform Solr queries and display Solr data in different ways.
This module requires the following modules/libraries:
- Islandora
- Tuque
- Apache Solr - 4.2 or higher.
Install as usual, see this for further information.
Set the 'Solr URL' and select a 'Request handler' in Administration » Islandora » Solr Index (admin/islandora/search/islandora_solr).
Islandora Solr Search offers many more configuration options in Administration » Islandora » Solr Index » Solr settings (admin/islandora/search/islandora_solr/settings).
Islandora Solr Search also implements the Islandora Basic Collection solution pack's query backend to drive the collection display using Solr instead of SPARQL/Fedora. This functionality can be applied on the collection solution pack's configuration page (admin/islandora/solution_pack_config/basic_collection), and that same page provides settings for sorting the Solr collection view globally and per-collection. The query backend relies on the relationship fields in the "Required Solr Fields" section of the Solr settings; the fields in that section should be confirmed before using Solr to drive the display.
To enable breadcrumbs, browse to Administration » Islandora » Configuration and choose Islandora Solr under Breadcrumb generation.

Q. Why are some dates not rendered correctly?
A. On 32 bit systems, the PHP function strtotime() has a limited range. Typically from Fri, 13 Dec 1901 20:45:54 UTC to Tue, 19 Jan 2038 03:14:07 UTC. For more info see this.
Q: Why can't I connect to Solr via https?
A: The Apache Solr PHP Client that we use does not support https connections to Solr. ISLANDORA-646 seeks to remedy this.
Q: Advanced search on PID worked in 6.x. Why do I get no results for the same search in 7.x?
A: In 7.x the colon in a PID must be escaped (i.e., islandora:34 becomes islandora:34) or the entire query must be wrapped in quotation marks (i,e., "islandora:34").
