Dynamically building the value of a field upon indexing

["Villemos, Gert" <ge...@logica.com>]

I would like to build the value of a field based on the value of multiple other fields at submission time. I.e. I would like to submit a document such as;
 
<field name="field1">foo</field>
<field name="field2">baa</field>
 
And would like SOLR to store the document as
 
<field name="field1">foo</field>
<field name="field2">baa</field>
<field name="aggregated">foo:baa</field>
 
Just to complicate matters I would like the aggregated field to be the unique key.
 
Is this possible?
 
Thanks,
Gert.

I think the SignatureUpdateProcessor does exactly what you want ... you 
just need a Signature implementation that does a simple concat (instead of 
an MD5)

so we have a simple identity signature? .. it seems like it would be 
trivial.

Thread Hijacking on Mailing Lists

When starting a new discussion on a mailing list, please do not reply to 
an existing message, instead start a fresh email.  Even if you change the 
subject line of your email, other mail headers still track which thread 
you replied to and your question is "hidden" in that thread and gets less 
attention.   It makes following discussions in the mailing list archives 
particularly difficult.
