The reindexer will not reindex all documents every time there is a
change.  It will try to minimize the work to only those fragments that
need the indexing.

However, when you know you need an index, why not add it before you
add the new content?  Even though the reindexer will minimize the
work, it will still need to reinsert the fragment, and there will
likely be merges too.  The reindexer would still need to be enabled to
reindex the existing 12 GB (if such reindexing is needed) but the data
you load after adding the index would be indexed when it is added to
the db.
