Bug 82743 [Markers] improved problem filter needed (OR clauses)
when working with large workspaces I find the current problems filter not powerful enough. If I were able to AND and OR the conditions available from the UI then I would solve all my use cases. my most needed one is : I would like to see ERRORS anywhere in the workspace OR WARNINGS in the current selected project

protected void updateFilterFromUI() {
        ProblemFilter filter = (ProblemFilter) getFilter();
        filter.setContains(descriptionGroup.getContains());
        filter.setDescription(descriptionGroup.getDescription().trim());
        filter.setSelectBySeverity(severityGroup.isEnabled());
        int severity = 0;
        if (severityGroup.isErrorSelected()) {
            severity = severity | ProblemFilter.SEVERITY_ERROR;
        }
        if (severityGroup.isWarningSelected()) {
            severity = severity | ProblemFilter.SEVERITY_WARNING;
        }
        if (severityGroup.isInfoSelected()) {
            severity = severity | ProblemFilter.SEVERITY_INFO;
        }
        filter.setSeverity(severity);
        super.updateFilterFromUI();
    }
