When teaching Boolean I always do a little exercise after explaining the
three operators by looking around the room and coming up with examples
using the kids --like: everyone with blond hair AND blue shirts stand
up, blond hair OR blue shirts; blond hair NOT blue on the shirt. They
love to look around see if someone is not standing who should be or vice
versa. Two or three of these examples and most of the time they have
it. It allows them to stand and stretch a little too. I then go to a
search and being from Chicago we try Chicago Bears or Chicago Cubs with
the Boolean operators. Since we use Follett, most of the kids have been
exposed to the OR operator for their advanced search.

Subject: Re: [LM_NET] Good Boolean search topics
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.
