Ok, so the datasources for you search engine, your source of information
will be files on different servers.
This is perfectly fine.
Lucene/Solr don't use the physical files you want to index for search.
You feed Solr with the Documents, which will be indexed, producing an
Inverted index and a set of inherent data structures to provide Search at
query time.
What you do really care is whether the index(es) related to your corpus of
Documents will be or not distributed across different nodes.

So, considering now the "files" to be index segments, the answer is yes.
Lucene can search between different indexes and Solr on top of it can as
well.
SolrCloud allow you to architect your Search Engine on a cluster of Solr
instances.
Each logic Collection can be partitioned in different shards ( partition of
the whole index) and each shard can be replicated how much you want.
It is possible to implement you own routing strategy ( the way your docs go
into which shard), or use already available routing strategies.
Yo may be interested in the compositeId routing, which later applies to
your search requirement.
Take a look to those interesting docs :
https://lucidworks.com/blog/multi-level-composite-id-routing-solrcloud/
https://lucidworks.com/blog/solr-cloud-document-routing/
At indexing time you will be able to calculate the shard to send your
documents, and be able to have your documents co-located depending of a
specific key ( that can be the original server the doc is coming from)

>
Now you can use at query time the same key you configured at Indexing time
and query only a subset of documents, based on their original location.
