{"brief":"The user asked verbatim: “List all search engines existed in history. Make sure not to miss any modern ones.” Treat “all” as an open-ended historical catalogue rather than a provably complete universe: no authoritative registry exists, names and brands change, regional and short-lived engines are poorly archived, and the boundary between web search, directories, portals, vertical search, metasearch, and AI answer engines is fuzzy. State this limitation prominently and do not claim literal completeness.\n\nThe research scanned broad historical timelines and lists plus modern, regional, specialized, privacy, decentralized, and 2023–2026 AI-search sources. After normalization and evidence thresholds, it produced 1,253 catalogued public-facing search-service names. Of these, 390 have a sourced launch year, from 1982 through 2026; 100 are explicitly ended/inactive by available fields; and 258 are classified somewhere in the source evidence as AI search or answer-engine names. Many statuses and dates remain blank rather than guessed. The modern search specifically included 2026 material, current as of 2026-08-31.\n\nr53de7ff9f34 is the full catalogue, one row per normalized service name, ordered by launch year then name. It has launch/end year when sourced, reported status, region, category labels, number of independent source URLs mentioning the name, and a clickable best source. Make this searchable/filterable and downloadable. Lead with one bold visual timeline or era view, but keep the complete table central because the user explicitly requested a list. Allow filters for launch era, status, categories (especially AI search / answer engines), and region. Do not infer “active” from a blank end year; display blank as unresolved.\n\nr1f191a7c1c8 contains precomputed totals and era counts. Use it for KPI cards and an era chart; do not calculate counts yourself. Emphasize the explosion of modern AI-search names in the 2020s and the large unresolved-date pool, which reflects incomplete historical documentation and permissive inclusion rather than a clean census.\n\nVisual style: beautiful archival-to-futuristic “history of search” design, excellent typography and readability, a chronological hero visual, compact KPI cards, and a highly usable catalogue. Clearly distinguish sourced fact, reported classification, and missing data. Add a methodology/definition note: included public-facing WWW search engines, metasearch services, search portals, notable vertical/specialized engines, decentralized/privacy engines, and named AI answer/search products; excluded site-internal search boxes, browser find, desktop-only local file search, enterprise-only software, and API-only products without a public search experience. Warn that false positives may remain in such a broad catalogue and invite readers to treat it as a living research index, not a mathematically exhaustive registry.","result_set_ids":["r53de7ff9f34","r1f191a7c1c8"],"title":"A Living History of Search Engines (1982–2026)","prev_report_token":null}
