If this is what you need, this (Lucene Java) conostructor would do:
IndexWriter(File path, Analyzer a)
Constructs an IndexWriter for the index in path, creating it
first if it does not already exist, otherwise appending to the existing
index.
Your current code really cannot work, becuase for FSDirectory.get(),
create=true, which erases everything first, and for IndexWriter(),
create=false, which expects an existing index.
