Issue
I want to know why an Issues search such as “does not have myCustomTag” or “title is myTitle” returns issues that still contain events that do not match that condition.

Resolution
Issue search returns any issue that has at least one event matching your filter. It does not mean every event in that issue matches.
Events in the same issue can differ - tags, titles, and other fields. Grouping still puts them together unless you change how issues are grouped. So an issue with 100 events can show up in your results even if only 10 match.
You cannot search for issues where every event matches. Instead:
Open the issue. On Issue Details, your filter stays applied and you only see the matching events. See Event Search.
Run the same search in Explore → Errors to look at matching events directly.
Use custom grouping if you want matching and non-matching events in separate issues. See Issue Grouping.
