The Search API Attachments module indexes the content of attached files (.txt, .pdf, etc.) using Solr. In this video, I will show you how to configure the Search API Attachment module to do that.

Install module

• Search API Attachments

Enable module

• Go to "Modules" (admin/modules) and enable:
  • Search API attachments
• (Save Configuration)

Configure Search API Attachments

• Go to "Configuration => Search and metadata => Search API => Search API attachments"
  • Extraction method: Solr
• (Save configuration)

Now, we need to add the attachment field to the list of fields to index.

• Go to "Configuration = > Search and Metadata => Search API (/admin/config/search/search_api)
• Node index
  • Click the dropdown arrow
  • Choose "Fields"
  • Add related fields
    • File attachments
  • (Add fields)
  • [x] Attachment » The file
• (Save changes)

Enabled data alterations

• Click "Filters"
• Data alterations
  • [x] File attachments (This will access the content of attached files and index it.)
• (Save configurations)

Index node

• Click "View" tab
• (Index now)

In video 10, I attached a text file to Item #1 that simply contains the text "Monday to Friday 8:00 am to 5:00 pm". Let's go home and search for the keyword "Monday" and click the "Search" button. As expected, it returns "Item #1" in the results. The word "Monday" isn't anywhere in any of the text fields, it's just in the file. So, this just shows that files can be indexed and searched.
