Using the most unhinged AVX-512 instruction to make fastest phrase search algo (gab-menezes.github.io)
Do you know when you go to your favorite search engine and search for something using double quotes, like a passage of a book/article or something very specific? That’s called phrase search (sometimes exact search). What we are telling the search engine is that we want these exact words in this exact order (this varies from search engine to search engine, but that’s the main idea).

What if GitHub had vector search? (manticoresearch.com)
GitHub’s search function can sometimes struggle, especially when you try to search by asking a direct question. This approach often leads to unrelated results, which can be frustrating. This issue is more noticeable when searching through issues or pull requests, where the details really matter.
