Practice question from Foundations of Modern AI Search
Fill-in: A system retrieves documents about "heart attack" when a user searches for "myocardial infarction" even though no exact words match. This capability demonstrates ____ search rather than keyword matching.
Answer
semantic
Explanation
Semantic search understands meaning and relationships between concepts, recognizing that "heart attack" and "myocardial infarction" refer to the same medical condition despite different terminology. Traditional keyword search would miss this connection because the exact words don't match.
