Hacker News Search
Finding the right information is a constant challenge for developers. Articles in this section look at search tools, indexing technology, and ways to dig through technical discussions and archives, alongside broader news about how search is evolving across the software industry.
Expect pieces on full-text search engines, ranking algorithms, and the craft of indexing large archives, together with practical guides to querying community discussion history. News about vector search and AI-assisted retrieval has become a regular theme as the industry rethinks how people find answers.
Search sits underneath almost every developer workflow, from debugging an obscure error to researching a library before adopting it. Engineers who build search features, and anyone who simply wants to find past technical wisdom faster, will recognize their daily problems in these stories.
Show HN: Shader Lab, like Photoshop but for shaders
