So, weekend is over.
here is some code :
private void addDocument(IndexWriter writer, File file ) throws
IOException, InterruptedException {
String path = file.getName();
log( "-------------start Indexing:" + path );
Document doc = null;
if(path.matches("\\d+_\\d{4}_[a-z]{2,3}\\.pdf")) {
doc = PDF_Document_Parser.getDocument(this,RealPath,file);
}
else if(path.matches("\\d+_\\d{4}_[a-z]{2,3}\\.txt")) {
doc = TXT_Document_Parser.getDocument(this,RealPath,file);
}
else {
log("do nothing");
}
log("doc: "+doc);
if( doc != null ) {
try {
writer.addDocument(doc);
}
catch(Exception ex) {
System.err.println("hallo1 "+doc);
ex.printStackTrace();
System.err.println("hallo2");
log("ERROR writer.addDocument(doc);");
}
}
else {
log( "Skipping " + path );
}
log( "-------------end Indexing:" + path );
}
Here is the output:
