Querying multiple tables
Using the Solr API to query multiple tables simultaneously having the same schema.
To map multiple Cassandra tables to a single Solr core, use the Solr HTTP API.
Specify multiple tables using the shards parameter. For
example:
http://host:port/solr/keyspace1.cf1/select?q=*:*&shards= host:port/solr/keyspace1.cf1,host:port/solr/keyspace2.cf2
Using the Solr API, you can query multiple tables simultaneously if they have same schema.
