-So far, so good. But this only handles the case where you want to match all of the specified keywords. Suppose instead, we wanted products whose description contains any of the supplied keywords. Our previous approach of chaining Where operators is completely useless! We could instead chain Union operators, but this would be inefficient. The ideal approach is to dynamically construct a lambda expression tree that performs an or-based predicate.

-Of all the things that will drive you to manually constructing expression trees, the need for dynamic predicates is the most common in a typical business application. Fortunately, it’s possible to write a set of simple and reusable extension methods that radically simplify this task. This is the role of our PredicateBuilder class.

-ExpressionStarter fixes this. As soon as the first expression is added to ExpressionStarter, the default experssion is removed. You can add the first expression by calling ExpressionStarter's Start method. However, calling Start is not required. If no expression has been added to the ExpressionStarter, then calling And or Or will simply add the first expresion. This is usefull when using loops.
