Reader in lucene's Text Field type and in java

[jitender ahuja <aj...@aalayance.com>]

Hi,
       Can anyone tell if the two : Reader in lucene's as Text Field type and the Reader class in java are the same and if yes, why so?
Also, if they are the same then does one must take the data input(even if from a XML Document from a database) from a Reader class or its relevant subclass. 
Regards,
Jitender

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

Yes, Reader is a java.io.Reader.  Why?  I guess my question is "why 
not?".

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.
