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. Without the hnsw feature the default is always 1, because that backend keeps the raw f32 and so has no precision to recover whatever the persisted tag says. 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.
