Code Search at Google: The Story of Han-Wen and Zoekt

• hound

  10 5,573 4.9 JavaScript

  Lightning fast code searching made easy

  

The same algorithm is also used in Hound (https://github.com/hound-search/hound) though I have to say the best implementation of code search by far that I've seen is https://grep.app

You really should check it out if you haven't already. It's incredibly useful; I used it all the time. Not open source though.

  Fast trigram based code search (by sourcegraph)

  

Russ Cox' trigram approach uses document IDs for the posting list, which makes the index much smaller, but gives less precise (ie. slower) matching. This is mentioned in the design doc at https://github.com/sourcegraph/zoekt/blob/main/doc/design.md....

• SurveyJS

  surveyjs.io featured
