Maintaining document TTL on replace

[Joe Weisblatt]

I'd like to replace document content without affecting the TTL that was set when the document was created.

But not supplying a TTL on replace seems to reset it to 0 (never expire) and I don't see how to retrieve the existing TTL on get.

Is my only option to explicitly store the expiration myself in the document content and explicitly reset it when I replace?!

Doesn't sound very elegant, to say the least.

Thanks,
