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
FieldNormModifier in contrib/miscellaneous.
However, as it is nearly impossible to extract the terms of
unstored fields, we might think of other ways.
Not impossible, just time consuming. The easiest way is to reconstruct
the token stream of each field using the term frequency vector. If you
haven't stored it there is a class called TermVectorAccessor in
contrib/miscellaneous that allows you to visit the term vector even
though it is not store, i.e. it will construct it be enumerating the
inverted index.
Remember that if you reconstruct a token stream via the term vector no
payloads will be available. If you use payloads it would be a simple
thing to patch TermVectorAccessor in order to set the payloads in the
tokens. Feel free to post such a patch in the Jira, it would be a nice
addition to that code.
