Hope this helps Use the BackgroundWorker. The following code assumes, you have a button 'button1' in your form, which executes the worker, which starts the long running task on a different thread:

Using "notify()" & "wait()" instead of "suspend()" and "resume()" to control

I wish did fix the issue. You have misunderstood how wait() works. Calling wait on a Thread object does not pause that thread; it instead tells the currently running thread to wait for something else to happen. To explain why, I'll need to back up a bit and explain what synchronized actually does.
When you enter a synchronized block you obtain the monitor associated with an object. For example,

code :

synchronized(foo) {

foo.wait();

class RepaintScheduler implements Runnable {
    private boolean paused = false;
    private final Object LOCK = new Object();

    public void run() {
        while (true) {
            synchronized(LOCK) {
                if (paused) {
                    try {
                        LOCK.wait();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                } else {
                    repaint();
                }
            }
            try {
                Thread.sleep(20);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }

    public void pause() {
        synchronized(LOCK) {
            paused = true;
            LOCK.notifyAll();
        }
    }

    public void resume() {
        synchronized(LOCK) {
            paused = false;
            LOCK.notifyAll();
        }
    }
}

public void init() {
    RepaintScheduler scheduler = new RepaintScheduler();
    // Add listeners that call scheduler.pause and scheduler.resume
    btn_increment.addActionListener(new ActionListener() {public void actionPerformed(ActionEvent e) {
        scheduler.resume();
    }});
    btn_decrement.addActionListener(new ActionListener() {public void actionPerformed(ActionEvent e) {
        scheduler.pause();
    }});
    // Now start everything up
    Thread t = new Thread(scheduler);
    t.start();
}

like below fixes the issue Elasticsearch and Solr are both based on Lucene and have very similar capabilities. Either would offer a wide variety of search syntax out of the box along with syntax highlighting and all the rest. Big comparison list here: http://solr-vs-elasticsearch.com
