Unfortunately, you can search code by file extension and phrase, and you can use advanced search to search for repository descriptions filtering by stars, but I don't believe you can do both at once.
For instance, searching for "flask" and limiting the results to >1000 stars returns only the 27 repositories with a matching description[0], but the code search returns over 4 million results, ignoring the stars parameter[1].
How would you build the search results UI for a grouped query like this? If one repository has 10k stars and has 1000 files with matching strings, should the first 1000 results be from the same repository?
For instance, searching for "flask" and limiting the results to >1000 stars returns only the 27 repositories with a matching description[0], but the code search returns over 4 million results, ignoring the stars parameter[1].
