Struct RecallFtsGatherConfig 

pub struct RecallFtsGatherConfig {
    pub enabled: bool,
    pub term_k: usize,
    pub selection_rule: RecallFtsSelectionRule,
    pub gather_mode: RecallFtsGatherMode,
    pub gather_limit: Option<u32>,
    pub gather_cap_multiplier: u32,
    pub cjk_bypass_ranked: bool,
}

Configuration for the FTS candidate-gather optimization (default: disabled, existing behavior).

Fields

enabled: bool

Enable the candidate-gather optimization. Default false = existing behavior.

term_k: usize

Max query terms to send to FTS after selection. Default 10 (existing fanout limit).

selection_rule: RecallFtsSelectionRule

How to select the K terms. Default original (existing order).

gather_mode: RecallFtsGatherMode

How the DB gathers candidates. Default ranked (existing behavior).

gather_limit: Option<u32>

Row cap for RankWithinCap gather. When None, uses candidate_limit * gather_cap_multiplier.

gather_cap_multiplier: u32

Multiplier for gather_limit when gather_limit is None. Default 4.

cjk_bypass_ranked: bool

When true, CJK queries bypass term selection and use the existing ranked all-term path.

Implementations

impl RecallFtsGatherConfig

pub fn from_env() -> Result<Option<Self>, RuntimeError>

Parse gather config from env vars. Returns None when none are set, Err on malformed values.

pub fn validate(&self) -> Result<(), RuntimeError>

Validate the config for internal consistency.

pub fn effective_gather_limit( &self, candidate_limit: u32, ) -> Result<u32, RuntimeError>

Compute the effective gather_limit for a given candidate_limit.

pub fn to_search_options( &self, candidate_limit: u32, ) -> Result<TextSearchOptions, RuntimeError>

Convert to DB-level TextSearchOptions for a given candidate_limit.
