A composite matching function is a special kind of matching function - one which encapsulate or comprises of one or more other matching functions.

Composite matching functions allow you to be much more precise about how you might match two values in the same column, in different records.

In particular, you can for example, assert that two different matching functions must both return true in order that the composite matching function as a whole returns true. If either of the two encapsulated functions returns false, then the composite function as a whole would return false.

Alternatively, you could assert that if either of two (or more) encapsulated matching functions were to return true, then the composite matching function as a whole would return true.

Currently, the following composite matching functions exist :-

There are a few things to bear in mind when using composite matching functions.
