Questions other engines cannot answer

Three pillars: keep the past (nothing is overwritten), live the future (continuous recrawl and standing queries), and visible ranking (every score has a breakdown you can re-weight).

Pages that gained a schema.org type this month

Most engines show you what a page is now. Here the question is what a page became: every refetch is a stored version with field-level change events. Sort by how many Wikipedia articles cite the page with sort=cited.

schema.added:Recipe changed_since:30d

Price drops across Product pages

History makes this a single query: price.dropped compares the structured price in consecutive versions. Each result carries the old and new value as evidence.

type:Product price.dropped changed_since:30d

Pages that changed their canonical

A classic SEO incident that is invisible without history. Every rel=canonical change is an event.

canonical.changed changed_since:90d

The web as of a date

as_of evaluates structured filters and returned fields as they were on that date, not as they are today.

type:Product price<50 as_of:2026-03-01

Highly cited, rarely changing

Wikipedia citations are a trust signal you can filter and rank on.

Why does A outrank B?

Compare two pages on a query, then re-score with the anchor-text weight turned down. Needs an API key.
