The encyclopedia of
agentic search
From finding a source to trusting an answer. Explore the ideas behind each part of the system, one working example at a time.
Where can the answer come from?
Source selection decides where an agent looks: the public web, a specialist collection, or an internal corpus. Coverage includes which records are searchable, how much content is accessible, and how recently it was updated. Finding a document in an index does not necessarily mean receiving its full text.
