title: Searching for file/class names in Netbeans does not work well
body: <p>I started using Netbeans (8.2) a few weeks ago and the search utility is driving me insane. Basically, I search for a class/file name in the top-right corner and it returns with no results, when in fact the class/file exists in the project. The same thing if I do cmd+O (go to type). This does not happen every time, but it happens a lot. Is this a bug? If not, can anyone enlighten me what I'm missing? Thank you in advance.</p>
