No documentation for the selector pathterm and no docs for modification 

We are planning to improve the modification tracking support so that it 
isn't necessary to build a custom tracker as is done in the example ... 
and then write documentation.

I think that for simple dependencies as illustrated in the example you 
can manage the updates, but if the selector is is subject to complex 
calculations it can be a challenge to to ensure that the index is 
updated correctly ..
