Using metadata of the requested files with Lucene
Hi All,
I'm trying to write a small app, ebook organizer, using Lucene.
I index metadata of various file types properly,and when I search a keyword
related to metada of documents I can get a result. However, I wanna get the
metadata of some specific indexed document e.g. I'll send the part/filename
to lucene, and it will return exact result including metadata of it. I
couldn't figure out until now. Any help is appreciated. Thanks!

You need to store the data in the index (Field.Store.YES) and then you
can get it back by calling doc.get("fieldname").

An example would help. But assuming you've indexed the part or
filename (and that it's unique), just search for it. You should
only get a single document back and then IndexReader.doc(luceneID)
will get you the stored for that document.
You have to watch out for tokenization of file names (use KeywordAnalyzer
perhaps).
Or you can just go to the term/doc directly, see TermDocs.
Best
Erick
