When I'm searching issues (by tag, search keyword or whatever), the list contains both resolved and unresolved issues.
When I filter on #unresolved issues in a particular project, and I click on a tag, it only shows that tag and ignores both filters (unresolved and project).
In many (not all) cases, it makes no sense to show already resolved issues. Please make it possible to hide resolved issues by default, for example by keep the filter settings when clicking on a tag.
And I'm not the only one: https://stackoverflow.com/questions/18577160/how-to-make-youtrack-not-show-solved-issues
