Re: appending field to an existing index
Thanks Chris! This works with lucene2.1 and greater (breaks with lucene2.0)
A follow up question, anyway to rename and to delete a field.
Rename field: I tried to use a hex editor to edit the .fnm file (screwed up
my index, but I was careful and followed the index format)
Deleting a field: ideas?
Thanks
-John
