- **A data library is required.** Ground Knowledge Similarity on an Agentforce Data Library in Data 360. Similar articles appear only when you set up a data library.
- **Enriched search index improves results.** For the most accurate matches, ground Knowledge Similarity on a data library that has an enriched search index.
- **Only indexed articles are compared.** Knowledge Similarity compares only articles that are indexed in the selected data library. For example, it doesn't return content that hasn't synced yet.
- **Similarity levels are relative.** The similarity level indicates how closely content matches. Use the similarity level as a guide, not an absolute threshold, and review matches before you act on them.
