Describe the bug

The usearch.h exact_search documentation doesn't match the function arguments

/**
 *  @brief Multi-threaded exact nearest neighbors search for equi-dimensional vectors.
 *  @param[in] dataset Pointer to the first scalar of the dataset matrix.
 *  @param[in] queries Pointer to the first scalar of the queries matrix.
 *  @param[in] dataset_size Number of vectors in the `dataset`.
 *  @param[in] queries_size Number of vectors in the `queries` set.
 *  @param[in] dataset_stride Number of bytes between starts of consecutive vectors in `dataset`.
 *  @param[in] queries_stride Number of bytes between starts of consecutive vectors in `queries`.
 *  @param[in] scalar_kind The scalar type used in the vectors.
 *  @param[in] dimensions The number of dimensions in each vector.
 *  @param[in] metric_kind The metric kind used for distance calculation between vectors.
 *  @param[in] count Upper bound on the number of neighbors to search, the "k" in "kANN".
 *  @param[in] threads Upper bound for the number of CPU threads to use.
 *  @param[out] keys Output buffer for up to `count` nearest neighbors keys.
 *  @param[out] distances Output buffer for up to `count` distances to nearest neighbors.
 *  @param[out] error Pointer to a string where the error message will be stored, if an error occurs.
 *  @return Number of found matches.

Under python/ index.search has an unused and undocumented argument radius

def search(
        self,
        vectors: VectorOrVectorsLike,
        count: int = 10,
        radius: float = math.inf,

Yes, @MarkReedZ, it has :) I was just discussing it with someone on a phone. Will think about implementing it in the engine 🤗
