is:issue is:open sustain*
which should match sustainable , sustainability etc.
GitHub provides a fairly elaborate search syntax, as explained here:
But it does not support partial searches, as discussed here:
Quote from GitHub staff:
Thanks for getting in touch - search doesn’t currently support partial searches, so in your example, you’re correct you would have to search for “feature”. Though not the same, we do however do some stemming for plurals - so searching for “features” would find “feature”.
This is much more problematic in languages with grammatical cases, such as German, Polish, French, Ukrainian, and many more. To give you an example the Polish word for function is funkcja but depending on the context it can be any of:
Without partial searches, you have to go through all of the variations to find the matching issues. This makes the search functionality barely usable in languages other than English.
If we were able to search by funkc , we could find all relevant issues in one go. It is a common functionality in search engines. Optionally this could be done with a wildcard, i.e. funkc*
