Islandora Collection Search

Islandora Collection Search is a Drupal module that allows for searching within a collection using Solr. It provides a more robust replacement for islandora_solr_search's 'Simple Search' block, and it automatically handles appropriate Solr re-indexes when records are moved between collections in Fedora.

Dependencies

This module requires the following modules/libraries:

• Islandora
• Islandora Solr Search
• Islandora Solution Pack Collection

Installation

1. Install as usual, see this for further information.
2. Ensure that a multivalued string field is being indexed in Solr containing the PIDs of each ancestor of an object. If you are using discoverygarden's basic-solr-config, this is the ancestors_ms field, which is not generated by default. A hierarchy.xslt template is provided in discoverygarden's islandora_transforms to traverse ancestors in the graph, from which such a field can be made.
   • The simplest way to enable this field is to use the latest version of basic-solr-config and the discoverygarden fork of gsearch 2.9.x, then follow basic-solr-config's README.md to create a custom_parameters.properties file.
   • Otherwise, hierarchy.xslt will have to be manually implemented. If using the basic-solr-config's foxmlToSolr.xslt, there may be existing XSLT that can be uncommented to enable the indexing of ancestors; otherwise, you can manually add them. These sections include the code to call and use the ancestors template, the XSLT include statements required to use the ancestors template, and any required namespaces.
   • If newly implementing this field on an existing site with repository content, Solr will need to be reindexed.
3. Set up the 'Islandora Collection Search' block. It can replace the standard 'Islandora simple search' block.
4. Ensure the ancestors hierarchy field created in step 2 is configured in admin/islandora/tools/collection_search as the Ancestor field, as well as connection information for GSearch.

Configuration

Configuring the Module

The configuration page for the module can be found at yoursite.com/admin/islandora/tools/collection_search.

• The 'Ancestor field' is set to 'ancestors_ms' by default.
• Configure the 'GSearch Config' section with the proper credentials.
• The options in the 'Collections' section of that page provide ways to configure the UI, such as having a drop-down menu of certain collections that can be searched from anywhere on your site where the 'Collection Search' block is enabled.

Configuring the Block

The configuration page for the 'Islandora Collection Search' block can be found at yoursite.com/admin/structure/block/manage/islandora_collection_search/islandora_collection_search/configure. The main configuration you might want to do is to define which pages display the block for which Roles and/or Users. That can be managed in the 'Visibility settings' section of this block's configuration page.

Usage

This module provides a block that works like the 'Simple Search' block, but it can narrow the search to objects within a given collection. However, it also has the option to search all collections, which would result in functionality identical to the 'Simple Search' block.

If all the Installation and Configuration steps have been successfully completed, the powerful and user friendly 'Collection Search' block should now be available.
