Switch from database search backend to Solr backend

Watch a video tutorial on how to switch an existing site from the database backend to a Solr server. This requires a Solr server to be configured in your environment.

Edit the “Solr search” server from the Search API configuration admin/config/search/search-api.
Add the configuration information for your Solr server. Refer to Drupal’s Search API Solr project for troubleshooting connection information.
Save the server and observe that Search API has successfully connected to your server.
Edit the “Search content” index and change the “Server” field to the newly configured “Solr Search” index.
Visit the “Search content” index and click “Index now” to re-index the content.

Layout Builder and Solr search

Solr search can be used with Layout Builder, and requires a few extra steps.

Configure Solr to index the new content types

In order for Solr to index the new content types, they need to be added to the index.

Enable the YMCA Website Services Search API (openy_search_api) module if not already enabled.
Go to Admin > Configuration > Search and metadata > Search API, then Edit the Search content index. (/admin/config/search/search-api/index/search_content/edit)
Configure Solr to index the Layout Builder content types:
- Scroll down, expand Configure the Content datasource, and check the content types that should be indexed for search.
- Save the form.
Configure how Solr indexes the Layout Builder content types:
- From the Search API configuration, open the dropdown for the Search content index and choose Fields.
- To the right of the Rendered HTML output field options, choose Edit.
- For each newly added content type, switch “Don’t include the rendered item” to the right view mode.
  - In general, new Layout Builder specific content types will use the “Default” view mode, while older Layout Builder-compatible content types should use the “Full content” view mode.
    Content type View mode
    Article (LB) Default
    Branch Full
    Event (LB) Default
    Camp Full
    Camp Subpage Full
    Facility Full
    Landing Page (LB) Default
    Program Full
    Program Subcategory Full
  - Save the page.
Once your changes have been saved, re-index the content to see the changes reflected in search results.

Content type	View mode
Article (LB)	Default
Branch	Full
Event (LB)	Default
Camp	Full
Camp Subpage	Full
Facility	Full
Landing Page (LB)	Default
Program	Full
Program Subcategory	Full

Set up a Layout Builder search page

If you have an existing site, disable the old search page:
- Go to /search.
- Remove the URL alias by unchecking Generate automatic URL alias in the sidebar then deleting /search.
- Uncheck Published and Save to un-publish the page.
Create a new Landing Page (Layout Builder) (node/add/landing_page_lb):
- Set the Title to “Search”.
- Ensure Generate automatic URL alias is unchecked in the sidebar and set the alias to /search.
  - If that alias results in an error, you can remove the old one at Admin > Configuration > Search and metadata > URL aliases
- Check Published then Save and edit layout.
Add a Small Banner to the header with a title for the page, like “Search”.
Add the search results block to the page:
- In the Body section, Add block, then expand All system block and choose Content search block from the Paragraph Blocks section.
- Optionally, choose to hide the title or change the number of items to display.
- Save layout and check your page.
Change the Search API config to use your new page:
- Go to Admin > YMCA Website Services > Settings > Search API settings (/admin/openy/settings/search-api) and set the Search page id to the node id of your new page.
- Or, change the config with drush:
```
drush cset openy_search_api.settings search_page_id <nid>
```
Test the search box in the Layout Builder page header to ensure the new configuration works as expected.

Legacy Solr Support

The contrib Search API Solr module supports a broad swath of Solr versions, but occasionally old versions are dropped from support in the main module. If, when enabling YMCA Website Services Search API, you encounter errors that your version of Solr is out of date, you may need to enable the Search API Solr Legacy module. As of January 2022, Search API Solr Legacy supports Solr 3.6 through 6.4.

The error message when using an old version of Solr may look something like this:

Notice: Undefined index: 4.x in Drupal\search_api_solr\Controller\SolrConfigSetController->getConfigFiles()
