Querying multiple tables
Query multiple tables by using the shards parameter.
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.
