public List getDuplicates
I'm not at all sure what you're asking.
I believe you can use a TermEnum with an empty term ("") to get all the
terms in a particular field.
If you're asking "how can I find all the fields in a document", well, that's
tricky. Since there's no requirement that every document have the same
fields,
any one know how to get the unique fields from the field in the lucene
index.

It's simple enough. Every time we're about to process a new item we
look in the database to see if there is already an item with the same
ID. If there isn't,

2. Is there an effect method to check if there exists the duplicate
fields(hold a unique ID) in the lucene index database? Two methods:
Read all documents and compare the fields, or search for each field.
Is there a better one
