Use abstract classes as super typs for Acknowledge operations

Currently we have a marker interface for Acknowledged[Request|Response],
this makes not much sense since we duplicate the code in each subclass
or class that implements the interface. We can simply use abstract
classes and have it implemented only once.

Highlighting can return excerpt with no highlights

You can configure the highlighting api to return an excerpt of a field
even if there wasn't a match on the field.

The FVH makes excerpts from the beginning of the string to the first
boundary character after the requested length or the boundary_max_scan,
whichever comes first.  The Plain highlighter makes excerpts from the
beginning of the string to the end of the last token before the requested
length.
