Struct RuleSearchRetrievalOptions 

pub struct RuleSearchRetrievalOptions<'a> {
    pub query: &'a str,
    pub lexical_query: &'a str,
    pub top_k: usize,
    pub confidence_map: Option<&'a HashMap<String, f64>>,
    pub age_days_map: Option<&'a HashMap<String, f32>>,
    pub target_file: Option<&'a str>,
    pub repo_scopes: &'a [String],
    pub ann_enabled: bool,
    pub embedding_timeout: Option<Duration>,
    pub cold_start_retry: bool,
    pub adaptive_prune: bool,
}

Options for the CLI/MCP search-style retrieval helper. The helper fans out across repo scopes, applies the shared confidence + age decay inputs at the retrieve_rules_with_confidence layer, merges duplicates, then applies the same lexical re-rank used by the MCP search tools.

Fields

query: &'a str

lexical_query: &'a str

top_k: usize

confidence_map: Option<&'a HashMap<String, f64>>

age_days_map: Option<&'a HashMap<String, f32>>

target_file: Option<&'a str>

repo_scopes: &'a [String]

ann_enabled: bool

embedding_timeout: Option<Duration>

cold_start_retry: bool

Retry a timed-out query embed once with a longer cold-absorbing budget (see embed_query_aligned_to_index). Set by the human-waiting CLI path so a cold first recall keeps semantic ranking; left false by the latency-critical hook/MCP callers that must fast-degrade to lexical.

adaptive_prune: bool
