请问HN：工程师和发明人在实际操作中是如何进行现有技术检索的？
对于从事发明或标准工作的人来说，您通常是如何进行先前技术检索的？<p>关键词搜索似乎在一定程度上有效，但我发现当同一技术概念在专利、论文或标准文件中以非常不同的方式描述时，这种方法就会失效。我也尝试过超越纯关键词搜索的方法，但对于细微的技术概念来说，这些方法仍然显得脆弱。<p>我很好奇人们在实际操作中依赖的是什么——大量的查询迭代、分类、特定工具，还是其他什么？我很想听听其他人哪些方法效果好（或不好）。

For people working on inventions or standards, how do you usually approach prior-art searching?<p>Keyword search seems to work up to a point, but I’ve found it breaks down when the same technical idea is described very differently across patents, papers, or standards documents. I’ve also tried approaches beyond pure keyword search, but they still feel brittle for nuanced technical concepts.<p>Curious what people actually rely on in practice — lots of query iteration, classifications, specific tools, or something else. Would be interested in hearing what’s worked well (or badly) for others.
