> There is a very significant potential for optimizing the size of the search
> index.
> We have seen a case where there were multiple segments with about the same
> number of nodes (roughly 10 million), but the size on disk was very different.
> One segment was 19 GB while all others where around 3 GB. The major
> difference was the number of fields indexed. The large segment had
> significantly more fields, which resulted in a large norms file.
> We should go through our implementation and see where norms are really
> necessary and disable tracking of norms wherever possible.
