Hi Lebiram,
contrib/misc contains a couple of tools that might be of help.
Just wanted to reconstruct a new index based on an existing
index(but turning off norms) that's all.
If you want to create an identical index but without norms use
FieldNormModi

Actually, you can reconstruct the text, but it's a lossy process. Stop words
aren't in the index for instance. And
Actually, you can reconstruct the text, but it's a lossy process. Stop words
aren't in the index for instance. And it's very time-consuming. Luke makes
a "best guess" at this process, so you might want to take a look at that
code. But even the very bright folks who put Luke together caution that
it
That is my understanding of it too. Terms in the index will point to the
position of the tokens they map to. Since one index term can point at any
number of tokens, this isn't a sequence map, but just a search map. If you
still have the text that was indexed you could run it through an analyzer
I am not sure but from my understanding fields that are only indexed and not
stored do not keep position. So even if you get back all terms for a field
for a given document you won't be able to reconstruct original words
sequence.
And remember that not all words are indexed.
