Hi Henrique,
I don't believe there's an easy way to do that.
As you noticed, the SolrInputDocument is not an I/O param, that is, it is
not sent back once data has been indexed and this is good, because here
you're sending just one document, but imagine what could happen if you do a
bulk loading...the response would be very very huge!
Although I could imagine some workaround (with a custom
UpdateRequestProcessor and a custom ResponseWriter), the point is that (see
above) I believe it would end in a bad design:
- if you send one document at time this is *often* considered a bad
practice;
- if you send a lot of data the corresponding response would be huge, it
will contains a lot of new created identifiers....and BTW how do you match
them with your input documents? Sequentially? mmmm....in this way you won't
be able to use any *asynch* client
Personally, if that is ok for your context, I'd completely avoid the
problem moving the logic on the client side. I mean, create a UUID field on
Solrj and add that ID to the outcoming document.
Best,
Andrea
