one mistake in this code
should be
infos.counter = ++counter;
instead of
infos.counter = counter++;

I've used following code to recover index. Note: it only works with
.cfs files.
String path = // path to index
File file = new File(path);
Directory directory = FSDirectory.getDirectory(file, false);
String[] files = file.list(new FilenameFilter() {
public boolean accept(File dir, String name) {
return name.endsWith(".cfs");
}
});
SegmentInfos infos = new SegmentInfos();
int counter = 0;
for (int i = 0; i < files.length; i++) {
String fileName = files[i];
String segmentName = fileName.substring(1,
fileName.lastIndexOf('.'));
int segmentInt =
Integer.parseInt(segmentName,Character.MAX_RADIX);
counter = Math.max(counter, segmentInt);
segmentName = fileName.substring(0, fileName.lastIndexOf('.'));
Directory fileReader = new
CompoundFileReader(directory,fileName);
IndexInput indexStream = fileReader.openInput(segmentName + ".fdx");
int size = (int)(indexStream.length() / 8);
indexStream.close();
fileReader.close();
SegmentInfo segmentInfo = new
SegmentInfo(segmentName,size,directory);
infos.addElement(segmentInfo);
}
infos.counter = counter++;
infos.write(directory);

Suppose I have a bunch of valid .cfs files while the
segmens/segments.new file is missing or invalid.
The task is to 'recover' the present .cfs files into a valid index.
I think it will be necessary and sufficient to create a segments file
that references the .cfs files.
The only problem I've encountered in generating a vaild and
well-formed segments file is that I need to know the number of docs
in each cfs file.
So the couple of questions is:
Do I have to put the right number of docs for each segments or any
(dummy) number will do?
If I have to put the right number there, how do I get it having the
cfs file?
