public interface DocumentBuilder

Creating an Index

Use DocumentBuilderFactory to create a DocumentBuilder, which will create Lucene Documents from images. Add this documents to an index like this:

 System.out.println(">> Indexing " + images.size() + " files.");
 DocumentBuilder builder = DocumentBuilderFactory.getExtensiveDocumentBuilder();
 IndexWriter iw = new IndexWriter(indexPath, new SimpleAnalyzer(LuceneUtils.LUCENE_VERSION), true);
 int count = 0;
 long time = System.currentTimeMillis();
 for (String identifier : images) {
 Document doc = builder.createDocument(new FileInputStream(identifier), identifier);
 iw.addDocument(doc);
 count ++;
 if (count % 25 == 0) System.out.println(count + " files indexed.");
 }
 long timeTaken = (System.currentTimeMillis() - time);
 float sec = ((float) timeTaken) / 1000f;

 System.out.println(sec + " seconds taken, " + (timeTaken / count) + " ms per image.");
 iw.optimize();
 iw.close();
