Documents modified recently score higher using exp(-ageDays/365) decay — a page modified today gets +256 points, one modified a year ago gets +128, two years ago +64. Skipped when moddate is unavailable. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Queries containing news-related terms (today, latest, news, breaking, recent, update) or year patterns get a 3x or 2x freshness multiplier, making recently-modified documents rank significantly higher for time-sensitive searches while keeping normal queries unaffected.

year-based query (e.g. "python 2024") gets up to +512.
