Subject: Re: Re-indexing a particular field only without re-indexing the
 entire enclosing document in the index

There's no update-in-place, currently you _have_ to re-index the
entire document.

But to the original question:

There is a "limited join" capability you might investigate that would
allow you to split up the textual data and metadata into two different
documents and join them. I don't know how well it scales, but it may
fit your needs.

It turns out that update-in-place is more than a bit difficult given the
nature of the inverted index. There are some proposals for addressing
this, but nothing has gotten beyond the design stage as far as I know.

Best
Erick
