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/MarkerView.java
uiJob.schedule();
        try {
            uiJob.join();
        } catch (InterruptedException e) {
            uiJob.cancel();
            monitor.done();
        } finally {
            if (monitor.isCanceled()) {
                uiJob.cancel();
            }
        }
        monitor.done();
    }
    /**

     * changes will be scheduled in a background job, and may not take effect

    protected void refresh() {
        if (uiJob == null)
            createUIJob();
        if (refreshJob == null) {
            refreshJob = new RestartableJob(Messages.format(
                    "MarkerView.refreshTitle", new Object[] { getTitle() }),
                    new IRunnableWithProgress() {
                        public void run(IProgressMonitor monitor)
                                throws InvocationTargetException,
                                InterruptedException {
                            internalRefresh(monitor);
                        }
