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
bundles/org.eclipse.ui.ide/src/org/eclipse/ui/views/markers/internal/DialogBookmarkFilter.java
filter.setContains(descriptionGroup.getContains());
        filter.setDescription(descriptionGroup.getDescription().trim());
        super.updateFilterFromUI();
    }

    protected void updateUIFromFilter() {
        BookmarkFilter filter = (BookmarkFilter) getFilter();
        descriptionGroup.setContains(filter.getContains());
        descriptionGroup.setDescription(filter.getDescription());
        super.updateUIFromFilter();
    }

        descriptionGroup.updateEnablement();
    }

    protected void resetPressed() {
        descriptionGroup.setContains(BookmarkFilter.DEFAULT_CONTAINS);
        descriptionGroup.setDescription(BookmarkFilter.DEFAULT_DESCRIPTION);
        super.resetPressed();
    }
