If, on the other hand, you wanted to search just one shard, you can specify that shard by it's logical ID, as in:
http://localhost:8983/solr/gettingstarted/select?q=*:*&shards=shard1
If you want to search a group of shard Ids, you can specify them together:
http://localhost:8983/solr/gettingstarted/select?q=*:*&shards=shard1,shard2
In both of the above examples, the shard Id(s) will be used to pick a random replica of that shard.
Alternatively, you can specify the explict replicas you wish to use in place of a shard Ids:
http://localhost:8983/solr/gettingstarted/select?q=*:*&shards=localhost:7574/solr/ge
ttingstarted,localhost:8983/solr/gettingstarted
Or you can specify a list of replicas to choose from for a single shard (for load balancing purposes) by using the
pipe symbol (|):
http://localhost:8983/solr/gettingstarted/select?q=*:*&shards=localhost:7574/solr/ge
ttingstarted|localhost:7500/solr/gettingstarted
And of course, you can specify a list of shards (seperated by commas) each defined by a list of replicas
(seperated by pipes). In this example, 2 shards are queried, the first being a random replica from shard1, the
second being a random replica from the explicit pipe delimited list:
http://localhost:8983/solr/gettingstarted/select?q=*:*&shards=shard1,localhost:7574/
solr/gettingstarted|localhost:7500/solr/gettingstarted
Configuring the ShardHandlerFactory
You can directly configure aspects of the concurrency and thread-pooling used within distributed search in Solr.
This allows for finer grained control and you can tune it to target your own specific requirements. The default
configuration favors throughput over latency.
To configure the standard handler, provide a configuration like this in the solrconfig.xml:
1000
5000
The parameters that can be specified are as follows:
