if (args.length != 2) {
throw new Exception("Usage: java " + Indexer.class.getName()

}
File indexDir = new File(args[0]);
File dataDir = new File(args[1]);
long start = new Date().getTime();
int numIndexed = index(indexDir, dataDir);
long end = new Date().getTime();
System.out.println("Indexing " + numIndexed + " files took "
+ (end - start) + " milliseconds");
}
// open an index and start file directory traversal
public static int index(File indexDir, File dataDir)
throws IOException {
if (!dataDir.exists() || !dataDir.isDirectory()) {
throw new IOException(dataDir
+ " does not exist or is not a directory");
}
IndexWriter writer = new IndexWriter(indexDir,
new StandardAnalyzer(), true);
writer.setUseCompoundFile(false);
indexDirectory(writer, dataDir);
int numIndexed = writer.docCount();
writer.optimize();
writer.close();
return numIndexed;
}
// recursive method that calls itself when it finds a directory
private static void indexDirectory(IndexWriter writer, File dir)
throws IOException {
File[] files = dir.listFiles();
for (int i = 0; i < files.length; i++) {
File f = files[i];
if (f.isDirectory()) {
indexDirectory(writer, f);
} else if (f.getName().endsWith(".txt")) {
indexFile(writer, f);
}
}
}
// method to actually index a file using Lucene
private static void indexFile(IndexWriter writer, File f)
throws IOException {
if (f.isHidden() || !f.exists() || !f.canRead()) {
return;
}
System.out.println("Indexing " + f.getCanonicalPath());
Document doc = new Document();
doc.add(Field.Text("contents", new FileReader(f)));
doc.add(Field.Keyword("filename", f.getCanonicalPath()));
writer.addDocument(doc);
}
}
