SitecoreAI now provides more ways to discover and index documents. Using anchor indexing, site sources can now index documents linked from crawled webpages as separate searchable items.
You can configure rules to determine:
which crawled pages SitecoreAI checks for links,
which linked documents are indexed,
and how embedded metadata in those documents is mapped to fields in your source.
Note: PDFs discovered directly through a sitemap can also be indexed and have their embedded metadata mapped to fields.
