    As it aggregates code from different repositories, any changes or unavailability in source repositories can affect the reliability of search results.
  • Potential for Outdated Information

    I reimagined https://searchcode.com/ since I realised LLMs have issues when it comes to understanding code you want to integrate. Itโ€™s useful for looking though any codebase, or multiple without having to clone it. I use it when I have candidate libraries to solve a problem, or I just want to find out how things work.

  • Searchcode.com's SQLite database is probably 6 terabytes bigger than yours
    Searchcode doesn't seem to work for me. All queries (even the ones recommended by the site) unfortunately return zero results. Maybe it got hugged? https://searchcode.com/?q=re.compile+lang%3Apython. - Source: Hacker News / over 1 year ago
