The Text field also takes a String in an overloaded signature.

Yes, Reader is a  Why?  I guess my question is "why 

So yes, you must feed text into Lucene either as a String or, if the 
Text field w/ Reader fits what you want that field to do, with a 
Reader.  Keep in mind that using Field.Text with a Reader is a slightly 
different than Field.Text with a String.  The Reader one does _not_ 
store the contents in the index - it indexes and tokenizes, but does 
not store.  The reasoning, I presume, for this is that text coming from 
a Reader is going to be larger than just a String and you would likely 
not want to store it anyway.
