Samuel,
IndexWriter should be opened once and keep it open
until all documents are added to the writer, then close the writer.
modified sample code:
final IndexWriter writer = new IndexWriter(indexLocation, new
StandardAnalyzer(),true);
for (Iterator iter = someData.iterator(); iter.hasNext(); ) {
Item item = (Item) iter.next();
Document doc = new Document();
doc.add(Field.Text("id", Long.toString(item.getId())));
doc.add(Field.Text("title", item.getTitle()));
doc.add(Field.Text("description", item.getTitle()));
writer.addDocument(doc);
}
writer.optimize();
writer.close();
