Top 5 search engines for easy code searching

Reusing the code/frameworks ( either the in public domain or FOSS licensed code) is pretty common. But searching for useful code online is not very easy.The regular search engines like Google or Yahoo are not designed for code searching. Now there are few specialized code search engines which can fetch better result. Here are the top five code search engines

  1. Google Code Search
  2. Krugle
  3. Koders
  4. oreilly Code Search
  5. CodeBase

All the above engines allow you to search on Language (like Java, C etc) and license (like GPL, MIT etc). Except for oreilly code search, rest of them search the internet.
Oreilly code search contains the code from their books.Which currently contains over 123,000 individual examples, composed of 2.6 million lines of code all edited and ready to use.

    I’ve only used ‘Google Code Search’ but I’ll try these now.

    Thanks, I wish I’d known this when I was working in development. I’m taking note now!

    Thanks again. Have fun reading all of the Problogger submissions! :)

    That’s a useful list – I’ve only heard of Google Code Search as well.

    Check out my Problogger submission, which I think you’ll find is relevant: Top Five Essential Practices for Developing Software

    Thanks! This could really come in handy!

    These are all useful search engines. One benefit of over Google code is that we actually index the source code repository.

    If your project is not in our index, just submit your source control repository.

    Hope that helps.

    see google’s programmers search engine

    Devshots returns Google search results, but emphasize on programming related sites and resources. So the search result will be smart and accurate.

  8. I like Mint the best as well. Except, my accounts look absolutely nothing like those ones in the picture… Can I have some of your money?!?!?

    Wow, this article is nice, my younger sister is analyzing these kinds
    of things, thus I am going to tell her.

  10. We stumbled over here by a different web page and thought
    I should check things out. I like what I see so i am just following you.
    Look forward to looking into your web page repeatedly.

    pepole are pepole…

    Hands down, Apple’s app store wins by a mile. It’s a huge selection of all sorts of apps vs a rather sad selection of a handful for Zune. Microsoft has plans, especially in the realm of games, but I’m not sure I’d want to bet on the future if this …
