vector_search

Use vector similarity search combined with scalar attribute filtering to retrieve relevant results from a specified table. Define search parameters, such as the target vector field, output fields, and filter expressions, to refine and optimize database query results.

Instructions

Perform vector similarity search combining vector similarity and scalar attribute filtering in the Mochow instance.

Args:
    table_name (str): Name of the table to search.
    vector (list[float]): Search vector.
    vector_field (str): Target field containing vectors to search. Defaults to "vector".
    limit (int): Maximum number of results. Defaults to 10.
    output_fields (Optional[list[str]]): Fields to return in the results. Defaults to None.
    filter_expr (Optional[str]): Filter expression for scalar attributes. Defaults to None.
    params: Additional vector search parameters

Returns:
    str: A string containing the vector search results.
