Elasticsearch also supports bulk indexing of documents. The client provides an interface to bulk index too, but it is less user-friendly. In the future we will be adding "helper" methods that simplify this process.

The bulk API method expects a bulk body identical to the kind elasticsearch expects: JSON action/metadata pairs separated by new lines.

If you are specifying these manually, Nowdocs are probably the best method. Otherwise, when you construct them algorithmically, take care to ensure newlines ("\n") separates all lines…​including the last!

Bulk indexing.

$params = array();
$params['body']  = <<<'EOT'
{ "index" : { "_index" : "my_index", "_type" : "my_type", "_id" : "1" } }
{ "field1" : "value1" }

EOT;

$ret = $client->bulk($params);

​

Like the Bulk API, if you specify the index/type in the parameters, you can omit it from the bulk request itself (which often saves a lot of space and redundant data transfer):

Bulk indexing w/ explicit index/type.

$params = array();
$params['body']  = <<<'EOT'
{ "index" : { "_id" : "1" } }
{ "field1" : "value1" }

EOT;

$params['index'] = 'my_index';
$params['type']  = 'my_type';

$ret = $client->bulk($params);
