Fields

graph_name: String

query_text: String

Exactly one of {query_text, query} is required. query_text needs an embedding model on the gateway; query is a pre-embedded vector (model-free).

query: Vec<f32>

extra_queries: Vec<String>

optional multi-query; embedded + searched too

k: u32

── seed + expansion (mirrors GraphSearchExpandRequest) ──

vector anchors (top-k)

ef: u32

0 = default ef_search

depth: u32

BFS hops (0 = anchors only)

edge_type: String

empty = all

reverse: bool

max_nodes: u32

cap on expanded set

max_degree: u32

per-node fanout cap

as_of: u64

── bitemporal scope (reused on the durable graph edge codec) ──

valid-time point (0 = no bound)

tx_as_of: u64

transaction-time point (0 = current belief)

scope: String

── memory scope (residual node-property predicate; not an ACL) ──

matches props.scope (empty = any)

user: String

matches props.user (empty = any)

session_id: String

matches props.session_id (empty = any)

fusion: i32

── blending ──

RRF (default) | LINEAR

w_similarity: f32

linear weights (used when fusion = LINEAR)

w_recency: f32

w_graph_distance: f32

decay_half_life_ms: u64

recency half-life; 0 = server default (~180d)

now_ms: u64

reference epoch for recency (0 = wall clock)

use_reranker: bool

optional cross-encoder pass (no-op if absent)

use_mmr: bool

optional MMR diversification

mmr_lambda: f32

final_k: u32

results returned after rerank (0 = k)

use_ppr_distance: bool

graph_distance = Personalized PageRank stationary mass over the induced anchor-seeded subgraph (Zep node-distance / mention-reranker analogue, best-accuracy). unset/false ⇒ cheap 1/(1+hop) default. The server flag STATELET_GRAPHRAG_PPR=1 forces PPR on for all calls.

Implementations

impl GraphRagSearchRequest

pub fn fusion(&self) -> ScoreFusion
