Multiple Indexes with Apache Solr Is it possible to use multiple indexes with Apache Solr? We want to use different indexes depending on the environment id.
Setup multiple solr core's and then use settings.php to define for each environment as poster above said. 

If you are using ApacheSolr its like: 

$conf['apachesolr_environments']['my_env_id']['url'] = 'http://localhost:8983';


Just make sure your settings.php is not moved from server to server, if it is then use environment variable in apache:

SetEnv ENVIRONMENT development
SetEnv ENVIRONMENT staging
SetEnv ENVIRONMENT production


And use something like this in settings.php 

&lt;?php   
switch ($_SERVER['ENVIRONMENT']) { 
  case 'development': 
    $conf['apachesolr_environments']['my_env_id']['url'] = 'http://localhost:8983';
    break;
  case 'production': 
    $conf['apachesolr_environments']['my_env_id']['url'] = 'http://www.domain.com:8983';
    break;
}
