Struct AdaptiveOptions 

pub struct AdaptiveOptions {
    pub coverage_threshold: f64,
    pub evidence_per_term: usize,
    pub patience: usize,
    pub min_gain: f64,
}

自适应爬取的停止条件（pagesift 扩展 adaptive）。

每个查询词的“证据“是包含它的、互不相同的相关段落数；覆盖度是各词 min(1, 证据 / evidencePerTerm) 的平均值。覆盖度达到 coverageThreshold 时停止 （coverage_reached）；或者连续 patience 页带来的新相关内容都少于已收集的 minGain 时停止（saturated）。

Fields

coverage_threshold: f64

evidence_per_term: usize

patience: usize

min_gain: f64
