Struct RetrievalRequest 

pub struct RetrievalRequest {
    pub embedding: Vec<f32>,
    pub k: usize,
    pub filter: Option<FilterExpression>,
    pub index_names: Option<Vec<String>>,
    pub compute_priors: bool,
    pub timeout: Option<Duration>,
}

Query request to the RAG++ retrieval engine.

This is the primary input contract for retrieval operations.

Fields

embedding: Vec<f32>

Query embedding vector (must match index dimension)

k: usize

Number of candidates to retrieve

filter: Option<FilterExpression>

Optional metadata filter expression

index_names: Option<Vec<String>>

Optional: specific indexes to search (None = search all)

compute_priors: bool

Whether to compute priors from retrieved records

timeout: Option<Duration>

Optional timeout for the query
