Search using vector mode - pure semantic similarity search using embeddings.

Best For:

Natural language queries
Conceptual searches
Queries like “quiet place for business meetings” or “romantic anniversary destination”

How it Works:

Query is converted to a vector embedding
k-NN search finds hotels with similar embedding vectors
Results ranked by cosine similarity score

Note: Works best with descriptive, natural language queries rather than keywords.

Request Body Example
