how do re-get the doc after the doc was indexed ?
for example:
I indexed a doc with path=c:/books/appach.txt, author=Mike
After a long time, I wanted to modify the author to John.
But the quethion is how I can get the exact same doc fastly ??
My idea is to traverse the docs from id=0 to id=maxDoc(), and
retrive it with store fields, and check its path whether equals
path=c:/books/appach.txt.
Any better idea ??
thx

Sounds like you want path to be a unique key field. So, just do a Lucene
search with a TermQuery for the path, which should return one document. No
need to mess with Lucene internal doc ids.
