Avoid using common words like turbo, buick, boost, gn, car, stock, fuel, etc. These occur so often that the software decided that it is pointless to search for them. If fact, it acts as though those words don't appear in the archives. So, if you use one, the software claims that there's no documents that match.
For example, if I search for boost and creep, I get no documents, but if I just search for creep, I get a bunch. In fact, I get the same list as when I search for boost or creep.
The complete list of these words is here.
