Search Engine
Privacy
Information retrieval system that indexes content and ranks results using signals and models.
Definition
Search engines crawl and index content, then rank results using relevance signals and machine-learning models. They may log queries, clicks, and identifiers for improvement and advertising.
Why this matters
Why it matters: Query logs are highly sensitive and can enable profiling; privacy-preserving search reduces retention and identifier linkage.
Example
Example: A privacy-focused engine avoids storing IP addresses and does not build personalized profiles for ads.
