The Islandora Solr Settings page has configuration options for searching and displaying Islandora object properties, descriptive metadata, full text, and OCR data of stored in Solr.
This menu control how search results are displayed.
If you enable multiple display profiles, to grant your users the choice of switching between them, you will also have to add the Islandora Displays block to a region (such as a sidebar, or above the content) in admin/structure/block.
Enabling these options will place an icon for the respective option next to your Solr search results.
This section has options to set for which Solr fields display and how they are to be displayed in search results for the "List" and "Table" display profiles. The "Grid" and "Bookmark" profiles are not affected by these settings.
[To configure which fields display in result sets from "/islandora/repository/" requests, edit the template file islandora-basic-collection.tpl.php in the site's theme.]
Specify which metadata fields from Solr's index to display for each item in search results.
Check this box to limit the search results to display only the Solr fields entered in Display fields. This will affect the "List" and "Table" display only. The "Grid" display is fixed. To configure the metadata for the "Bookmark" display see Islandora Bookmark.
Enter a number for how many objects should appear on each page of search results.
Check this box to enable a block that gives users a previous/next browse through search results after selecting an item, as well as an option to return to the main list of search results.
You can expose this function to users by adding the Islandora search navigation block to a region (such as the First Sidebar or Second Sidebar) in admin/structure/block.
This menu lets you select fields that users can manipulate themselves to re-order the items on a search results page. These fields can be metadata fields or item properties ("fgs_" type fields) and those fields don't even have to be displayed fields. Or you can just specify relevancy.
The fields must not be multivalued fields in Solr. For more on this see Appendix D.
You can expose the sort fields to users by adding the Islandora sort block to a region (such as a sidebar) in admin/structure/block.
The default sort field is "score" which is a relevancy ranking based on how well the search query matches each result. The way that different fields are valued is configurable in Solr.
This is where you can specify terms that users can choose to help narrow down a result set to only those items that match that term, such as a specific subject heading, or were created by a specific author, or are of a certain type, or are within a certain date range.
Facet fields mut be non-tokenized strings in Solr. For more on this see Appendix D. As you type in the fields in "Add another item" the eligible Solr fields will be indicated with the word "(string)."
you can expose the facet to users by adding the Islandora facets block to a region (such as a sidebar) in admin/structure/block.
This is where you can build search queries that target specific Solr fields. The "Islandora simple search" block, by contrast, searches across a broad set of fields which you can configure here under Query defaults > Query fields.
Advanced search fields should be tokenized fields in Solr. All Dublin Core fields, for example, are tokenized. For more on this see Appendix D.
Default boolean operator - Specify whether search results must contain all (AND) of he search terms or any (OR) of the search terms in the query.
For example:
"User-configurable" means to let the user choose the boolean operator between the search terms.
You expose the Advanced search to users by adding the Islandora advanced search block to a region in admin/structure/block.
To present the Advanced search block on its own page, add the block to the "Content" theme region (the main section on a page). Then create a new Drupal node and set the Advanced search block to display on only that node.
This menu contains settings that apply to all Solr queries in Islandora. Installations of Islandora that have namespace restrictions must enter the namespaces here to restrict the search results to only the relevant namespaces. You can enter more than one namespace.
The values appearing in the figure below serve only as examples.
These Solr fields are required by Islandora in order to create a repository browse interface and manage Fedora objects. These fields are populated with default values and should probably not be changed.
This section contains a checkbox to turn "debug mode" on or off. Debug mode for Solr will show the text of Solr queries in the Drupal display, and generally should not be used in a production site.
Note:
Many of the options configured in the Solr Settings menus affect only searches and results sets associated with Solr searches. You can recognize a Solr search by the URL string "/islandora/search/...". Other types of searches, such as browsing using URLs like "/islandora/repository/" and some like "/islandora/object/..." will not be affected by some of the options set here in Solr Settings.
