Today I wanted to search for "strstr[a-z]+?_r" but got the error message "This is a partial result set. The search was stopped early because it would take too long to check every file for this regular expression.". However, I got results for the less restrictive regex "strstr.+?_r" which is weird since I'd expect that it would be easier to return results for more restrictive regular expressions. Not sure if there is a perfect solution for this, but in many cases, you could probably search for the less restrictive version and filter the results with the more restrictive one after that.
Also it would be great if more repositories were indexed. How do things work behind the scenes? Maybe it is possible to build a more memory-efficient index just for exact string search, which probably make up most searches.
Anyway, this website is amazing and I use it quite often. Thank you a lot for working on this!
* Copy & Paste does not work. When trying to select text from code snippets, the code is dragged like an image instead of being selected.
* The GitHub icon during search is not clickable. Clicking to the right of the GitHub icon does not go to GitHub but instead shows an embedded view of that repository. There, the GitHub icon somewhere on the right is a bit hard to find (maybe write "View on GitHub" next to it so it is discoverable with Ctrl + F?), but at least it is clickable.
Give it a shot and let us know what you think! Where can we improve it?
