> * if you create new Field("", ""), you get IllegalArgumentException from Field's ctor:
"name and value cannot both be empty"
> * But there are tons of other ways to index an empty term for the empty field (for example
initially make it "garbage" then .setValue(""), or via tokenstream).
> * If you do this, and you have assertions enabled, you will trip an assert (the assert
is fixed in trunk, in LUCENE-3526)
> * But If you don't have assertions enabled, you will create a corrupt index: test: terms,
freq, prox...ERROR [term : docFreq=1 != num docs seen 0 + num docs deleted 0]
