LIRE的使用：搜索相似的图片
使用?ImageSearcherFactory?创建?ImageSearcher。例如ImageSearcherFactory.createDefaultSearcher()。
?ImageSearcher?可以通过?InputStream?或?BufferedImage，或者一个描述图像的Lucene的?Document?进行检索。 例如使用search(BufferedImage, IndexReader)?或者search(Document, IndexReader).
返回的结果是一个?ImageSearchHits?类似于Lucene 中的Hits。
