Or simpler:
wr = new IndexWriter(indexDir, aWrapper, !IndexReader.indexExists(indexDir));

This look better?
// Check to see if index exists.
// If it doesn't, then set createIndex boolean to true
boolean createIndex = false;
if (!IndexReader.indexExists(indexDir)) {
createIndex = true;
}
// let's set up the index writer
wr = new IndexWriter(indexDir, aWrapper, createIndex);
wr.setUseCompoundFile(false);
