public interface ImageSearcher

Searching in an Index

Use the ImageSearcherFactory for creating an ImageSearcher, which will retrieve the images for you from the index.

 IndexReader reader = IndexReader.open(indexPath);
 ImageSearcher searcher = ImageSearcherFactory.createDefaultSearcher();
 FileInputStream imageStream = new FileInputStream("image.jpg");
 BufferedImage bimg = ImageIO.read(imageStream);
 // searching for an image:
 ImageSearchHits hits = null;
 hits = searcher.search(bimg, reader);
 for (int i = 0; i < 5; i++) {
 System.out.println(hits.score(i) + ": " + hits.doc(i).getField(DocumentBuilder.FIELD_NAME_IDENTIFIER).stringValue());
 }

 // searching for a document:
 Document document = hits.doc(0);
 hits = searcher.search(document, reader);
 for (int i = 0; i < 5; i++) {
 System.out.println(hits.score(i) + ": " + hits.doc(i).getField(DocumentBuilder.FIELD_NAME_IDENTIFIER).stringValue());
 }
