Comment on Long Read: Lessons from Building Semantic Search for GitHub and Why I Failedparent

Comments

https://manticoresearch.com/blog/github-semantic-search/ gives some good examples where you get more with semantic than keyword search:

  * Search for "memory leak", get "index out of memory"
  * Search "API rate limits", get “throttling”, “250 results” limit, and “rate limiting”
  * Search issues for "user authentication" to see whether anyone has submitted your feature request
  * Search for “SQL injection” to get “database infiltration” or “SQL vulnerability”

I understand that semantic search gives you more than keyword search. I don't understand the cases when you need that. Like I said, I use GitHub issues all the time, and it's exceedingly rare that I need to search for something extensively like this.
