When I taught Boolean operators to a group of student workers in our college, I gave a simple example of using dolphins and whales, having them search using those terms on the computers they were using during class. dolphins AND whales dolphins OR whales dolphins NOT whales Of course they got more hits with the OR operator, but one has to be careful in using the NOT operator with related terms because they might miss information that could be helpful to them. In other words, if one searches "dolphins NOT whales" they might miss out on books that have information on dolphins, but since the book contains whales also, the book will not show up. On the other hand, having a statement such as "computers AND net NOT fishing" will result in information about computers and computer nets but leave out anything regarding fishing, even though both terms use nets. Just something to share; hope it helps.
