Lyceum Search
Zero API · Zero Google · 76 US Cities · 9 Open Sources · Security-filtered · Top 20 by quality score
There are no API keys in this search engine at any level — not for you, not for the admin. Queries fire raw HTTP requests directly to open public indexes operated by non-profits, volunteers, and government agencies. No SerpAPI. No Google. No Bing. No search company involved in any step.
Common Crawl — non-profit, billions of pages. Internet Archive CDX — Wayback Machine index, great for .gov & newspapers. YaCy P2P — volunteer decentralised search network. Data.gov — US federal open data (Census, EPA, BLS, HUD). Wikipedia, Open Journals (DOAJ), Open Library, CrossRef, and Semantic Scholar — millions of academic papers, books, and research datasets.
Results are geo-scored by how many city/state terms appear in their URL, title, and snippet. Only results mentioning your selected cities rank above zero — eliminating billions of irrelevant global pages and keeping results focused on a few million relevant US sites. Select individual cities, all metros, or all university towns at once.
Medical clinics, dental offices, auto repair shops, construction contractors, churches, home service companies, and known e-commerce spam domains are filtered out automatically. Over 60 keyword and domain patterns blocked at the pipeline level before any result appears.
Pages below your minimum word threshold are excluded. Word count is estimated from page byte size (~24 bytes per word of HTML). At the default 10,000-word minimum, you see only substantive content — no thin marketing pages, no stubs, no auto-generated filler.
Every URL is checked against malicious TLDs, phishing domain patterns, known exploit path signatures, and URL heuristics. Keyword spam (density >12%, low lexical diversity, title template abuse, slug stuffing) is detected and penalised. Results are sorted by a 0–100 quality score weighted by domain authority, source credibility, content depth, geo-relevance, keyword match, and freshness.
