I am still fairly new to the Mac, had mine just over a month now. What has struck me is how slow spotlight is. I come from Windows 7, which has a fantastic instant search. I am not sure if my expectations of spotlight are off or if I have some issue I am unfamiliar with. I've researched this quite a bit. There do seem to be random complaints about spotlight. Usually people recommend getting more ram, rebuilding the index, or repairing permissions. I have tried repairing permissions, that is about it. I am not sure how the index is rebuilt, or I would be willing to try that. What seems to happen is sometimes I just do not get the results I want. I will type in a query, and wait for 10 - 20 seconds for the document I want to show up. It usually never does. If I delete the query, then try again immediately afterwards, the document I want shows up. Is this behavior expected? This is snow leopard fully updated on a Macbook Pro 2.53Ghz i5 and 4GB Ram with the 500GB 7200 RPM hard drive. While the query is running, I have Word, Outlook, Safari, and sometimes Xcode and the terminal open. Should I just leave it be, that is how it is, deal with it? Or is rebuilding the index something I have to do regularly, or maybe some other voodoo magic trick?
