Alejandro, you'll have to clarify how you are using the term "federated 
search". I mean, technically Ahmet is correct in that Solr queries can be 
fanned out to shards and the results from each shard aggregated 
("federated") into a single result list, but... more traditionally, 
"federated" refers to "disparate" databases or search engines.


So, please tell us a little more about what you are really trying to do.

I mean, is all of your data in Solr, in multiple collections, or on multiple 
Solr servers, or... is only some of your data in Solr and some is in other 
search engines?

Another approach taken with Solr is that indeed all of your source data may 
be in "disparate databases", but you perform an ETL (Extract, Transform, and 
Load) process to ingest all of that data into Solr and then simply directly 
search the data within Solr.

Federation is possible. Solr has distributed search support with shards

I have a general question about Solr in a federated search context.  I
understand that Solr does not do federated search and that  different tools
are often used to incorporate Solr indexes into a federated/enterprise
search solution.  Does anyone have recommendations on any products (open
source or otherwise) that addresses this space?
