One Search
Search across sources once.
OpenAlex, Crossref, Semantic Scholar, arXiv, CORE, Europe PMC, PubMed Central, DOAJ, OpenAIRE, and Unpaywall work together.
一次输入，统一检索多个学术数据库和开放仓储。
Full-text discovery without database hopping
不用在多个数据库之间来回切换，先找合法全文，再处理疑难文献。
Find papers once. Verify open full text before the paywall slows you down.
Search scholarly sources, repositories, and DOI routes together. Direct PDFs surface first; unresolved papers move into a human work order.
一次检索多个学术源与全文入口；能下载的先展示，难例再进入人工补位流程。
Why it matters
A research workflow built for dead ends.
Academic search is rarely one clean click. The platform reduces repeated database switching, filters false PDF links, and keeps hard cases traceable.
文献检索的难点不是没有入口，而是入口太分散、全文路径不稳定、人工跟进不可追踪。
Legal First
Surface open full text safely.
Verified PDFs, repository copies, preprints, and PMC records are prioritized. High-risk mirror downloads stay outside the product.
优先展示合法开放全文、仓储副本和预印本，适合长期运营。
Human Closure
Turn misses into work orders.
When automation cannot verify a PDF, users can submit a request. Admins complete the loop from a protected dashboard.
自动化找不到时不结束服务，而是进入人工补位。
From query to closure
Designed around the real paper chase.
The system does not just search. It validates, ranks, records, and escalates. That makes the service useful even when a paper is locked behind a login or subscription.
01
Normalize the paper identity
DOI, title, authors, journal, year, and citations are merged across sources.
先统一论文身份，减少重复与误判。
02
Verify open full text
PDF candidates are checked before being displayed as direct downloads.
展示前先过滤 XML、HTML、登录页和非 PDF 链接。
03
Route unresolved requests
Users submit a work order. Admins resolve it and notify users by email.
疑难文献进入后台工单，处理完成后邮件通知用户。
Built for researchers
Less time chasing access. More time reading what matters.
减少无效跳转、登录和重复检索，把时间留给真正的阅读、判断和研究。
Fewer Database Switches
Search across scholarly indexes, repositories, DOI resolvers, and biomedical archives from one place.
一个入口覆盖多个来源，不再反复切换网页。
Open Full Text First
Legal PDF candidates, repository copies, preprints, and PMC records are checked before manual requests.
先找可合法访问的全文，再处理疑难文献。
Human Follow-up
When automation cannot verify a PDF, the paper becomes a request instead of a dead end.
找不到也不会中断服务，可以进入人工跟进。
Ready for AI Reading
The service can grow into summaries, topic extraction, reading notes, and research recommendations.
后续可扩展为论文摘要、阅读笔记和研究建议。
Research should not stop at a paywall.
Search every open route first. Then close the hard cases by hand.
Use CleanTENGflight Research Assistant as the front door for literature discovery, full-text verification, and human follow-up.
把检索、合法全文定位、人工补位和邮件通知放进一个闭环。
