May I also ask wheter there is a way to use writer.optimize() without
indexing the files from the beginning?
It took me about 17 hrs to finish building an unoptimized index(finish when I call IndexWriter.close() ).I just wonder wheter this existing index could be optimized...
You can always open a new IndexWriter on your index, do things like
addDocument, optimize, etc., and then close it.
There's no requirement that you do addDocument / optimize in a single
session of IndexWriter.
But do be careful not to pass "create = true" to IndexWriter.
The trunk (soon to be 2.1 release) version of Lucene has new
IndexWriter constructors that "create when needed, else append", see
here:
