Subject Merging data from different sources
Date Tue, 30 Oct 2018 11:57:00 GMT

I am trying to merge files from different sources and with different content (except for one
key-field) , how can this be done in Solr?

An example could be:

Document 1
        <Id>0000001</Id>                                      Unique id for Document

Document 2
        <Id2>abcdefgh</Id2>                                   Unique id for Document

In the above case I would like to merge on Journalnumber thus ending up with something like

        <Id>0000001</Id>                                      Unique id for the
        <Id2>abcdefgh</Id2>                                   Reference id for
Document 2.

How would I go about this? I was thinking about embedded documents, but since I am not indexing
the different data sources at the same time I don’t think it will work. The ideal result
would be to have Document 2 imbedded in Document 1.

I am currently using a schema that contains all fields from Document 1 and Document 2.

I really hope that Solr can handle this, and any help/feedback is much appreciated.

Best regards
