Subject Re: Solr + Federated Search Question
Date Thu, 02 Oct 2014 16:29:37 GMT
Ahmet,Jeff,

Thanks.  Some terms are a bit overloaded.  By "federated", I do mean the
ability to query multiple, disparate, repositories.  So, no.  All of my
data would not necessarily be in Solr.  Solr would be one of several -
databases, filesystems, document stores, etc...  that I would like to
"plug-in".  The content in each repository would be of different types (the
shape/schema of the content would differ significantly).

Thanks,

Alejandro
