Islandora Solr Facet Pages provides alphabetical "A to Z" browse lists from metadata indexed in Solr. You can set up multiple A-to-Z browse lists from different facets (Solr fields). For example, this can be used to list all authors or all subject headings present in an Islandora repository.
Each facet page appears at /browse/my-configured-path.
This module requires the following modules/libraries:
Install as usual, see this for further information.
Configure facet pages at Administration » Islandora » Solr index » Facet Pages (/admin/islandora/search/islandora_solr/facet_pages).
Each facet page requires a solr field (the facet) and a path (so the page will be at /browse/{path}). The label, if present, is set as the Drupal page title.
When choosing Solr fields for facets, you probably want to select string fields. This depends on your Solr config, but often this includes fields ending in *_s or *_ms. Strings will display as full multi-word phrases. Text fields (often *_mt or the dc.* fields) will show raw parsed text (individual words or parts of words) and is usually not what is desired.
If you need to configure more pages than the form provides, save the full configuration form and more blank fields will automatically appear.
When the list of facets is long, it can be split over multiple pages using a pager. This variable sets the page size.
Set the maximum number of facet values to return, period. If this value is less than the number of values that exist in Solr, they will be pruned arbitrarily. However, lowering this value may improve page loading speeds.
Provide the user with a search form to search within these facets.
Search is case-sensitive and must match the entire facet value. Therefore, search does not work well on string fields, unless the user makes use of wildcards. For example, *Alice* would match that term anywhere within the string, while Alice would only match a full string value of "Alice".
This search form works more intuitively on text (e.g. *_mt) facets, but as mentioned above, raw tokenized values are generally not what is desired for display.
This module provides a block named "Islandora Solr facet pages" that can be configured in Block settings (Administration » Structure » Blocks). It contains a list of links to all configured facet pages.
This module provides template files for the entire page (islandora-solr-facet-pages-wrapper.tpl.php) and the results list (islandora-solr-facet-pages-results.tpl.php). The alphabetical pager uses a theme function.
Template files can be overridden by a theme by copying the template file from the modules folder into the theme folder. You can override a theme per defined facet page by appending the path value to the template file. If you do, make sure to copy the original template file to your theme as well.
The folder for a theme that customizes the Solr facet pages layout would look like this:
sites/all/themes/{your-theme-folder}
├── {other files}
├── islandora-solr-facet-pages-results.tpl.php
├── islandora-solr-facet-pages-results--{your-path}.tpl.php
└── islandora-solr-facet-pages-wrapper.tpl.php
