[Original] Based on Apache Lucene's MP3 search, a few days of old songs on the machine, tested some twists and turns, after thinking that these MP3 have their own label information, why not use it? The author tries to implement it with Lucene, divided into two parts, MP3Indexer.java is created, MP3Search.jsp is a page search for MP3. Here is the code of MP3Indexer.java. Package mp3indexer; import java.io. *; import java.text. *; import java.util. *;
Import org.apache.lucene.Alysis.cjk. *; import org.apache.lucene.document. *; import org.apache.lucene.index. *;

} catch (exception e) {system.out.println (E.getMessage ());}}
