Struct VectorSearchOptions 

pub struct VectorSearchOptions {
    pub k: usize,
    pub label: Option<String>,
    pub properties: Option<HashMap<String, Value>>,
    pub rescore_factor: Option<usize>,
}

Options for vector_search_with.

Fields

k: usize

Maximum number of results to return.

label: Option<String>

If set, only nodes carrying this exact label are included in results.

properties: Option<HashMap<String, Value>>

Optional property key-value filters. Only nodes matching all filters are returned.

rescore_factor: Option<usize>

Rescore factor. When greater than 1, search fetches k * rescore_factor candidates from the index and re-ranks them by exact distance against the full-precision vectors stored in LMDB. Defaults to 2 on a quantized index and 1 (no rescore) on a Float32 index. The default applies to filtered searches too, where the over-fetch means the traversal must find k * rescore_factor predicate-matching candidates; pass Some(1) to disable rescoring for a selective filter.

Trait Implementations
