Searching for Issues inside projects is not very user friendly.
1.Filtering searches returns irrelevant results where it seem the filter has not been applied at all (ex. screenshot). In this example, no issues in the results fit the seaarch and I know there are new, modified issues after the date specified in the search.
2. There is no option to search within the description, only "Name." In large projects it is very difficult to remember text in issue names but often easy to remember key ideas or words. A "free text" search of all issues would be helpful.
