Terry, With regular queries (non-Span-queries) you cannot request that results of OR / AND / NOT operations are near to one another (i.e. (A or B) near (C or D)). The span queries solve that problem by allowing any span query to be used in a SpanNearQuery (and vice versa). There are other applications for this as well, but this is one of them.
Hope that helps to get you started. Examples for the use can be found in the unit tests (TestBasics.java, I believe).

It's hard to extrapolate the terse unit test code into much of a general notion. I searched the archives with little success.
