Bug description

Currently searching for an issue number with a leading hashtag (e.g. #200) does not return issue 200. Searching for 200 does return the correct result.

Current behavior
Search query #200 → no results
Search query 200 → issue 200 is found

Expected behavior
Searching for #200 should return issue 200

I often copy issue numbers from Github an open issue in the browser which includes the hashtag.
