GitHub hosts 28 million public repositories. Do you think your IDE can open 28 million projects at once and search there "trivially" without hanging? Unless you're talking about searching inside a single repository?
I am talking about searching in a single repository, who would expect to get useful results otherwise? I have no idea how you’re going to rank 28 million repos in a way that matches my perception of relevance.
To be specific, I was looking for the definition of one method in Highcharts so I could understand what it does and override it, GitHub gave 6 pages of results. I was able to find the function immediately in my IDE once I checked out the 100mb+ repository and it indexed it. If I’d been able to the same w/ the search on GitHub it would have saved me considerable time and hassle.
This search could be implemented by something that compiles and indexes like the IDE (sourcegraph) or maybe some kind of shallower parsing. Highcharts is in typescript which I’d don’t know well but in JavaScript the later might be a little tricky because there are so many ways to define a function (one hell of a regency.). I’d contrast to Java where is would be very easy to write a rule that would turn up a class definition if not a method definition, in my case finding the class would have solved my problem.
Sourcegraph engineer here. I'd be interested to know what you were searching for and what your expectation for top result was. We already do things like boost class name matches higher than functions (GitHub's new search does the same) amongst other possible signals.
