The AgentForce Retrieval and Semantic Search Guide explains that vector search (semantic search) is best suited for handling spelling variations, synonyms, and phonetically similar queries. The documentation states:

“Vector search enables fuzzy matching through semantic embeddings, allowing retrieval of relevant documents even when user queries contain typos, abbreviations, or informal phrasing.”

Option A (hybrid search) is effective when combining structured and unstructured queries but is not primarily designed to handle spelling tolerance.

Option C (keyword search) relies on exact term matching and fails when users misspell words.

Therefore, Option B — vector search — is the correct solution for managing misspellings and similar word variations.
