In this work, we evaluate the performance of three alternative TTL mechanisms: time-based TTL, frequency-based TTL, and click-based TTL. Moreover, we propose hybrid approaches obtained by pair-wise combination of these mechanisms. Our results indicate that combining time-based TTL with frequency-based TTL yields superior performance (i.e., lower stale query traffic and less redundant computation) than using a particular mechanism in isolation.eninfo:eu-repo/semantics/openAccessWeb search engines; result caching; time-to-liveConference Object10.1145/2505515.2507886188118842-s2.0-84889579141N/AWOS:000722225900264N/A
