----------------------------------------------------------------

One small thing (I found this also in the LIA chapter):
"Trie" is the whole "prefix tree". So "trie" means the whole list of different 
precision terms for one numeric value. You have this explanation which suggests 
one trie is one term:
{code}
+ * <p>Within lucene, each numeric value is indexed as
+ * multiple encoded terms representing larger and larger
+ * pre-defined brackets called <em>trie</em>s.  The step
+ * size between each successive trie is called the
+ * <code>precisionStep</code> in this API.  Smaller
{code}
There should also be the explanation that the precStep is in "bits".
