Description

The following is the current Solr 3.1 format for sending multiple documents by JSON. It's not analogous to the XML method, and isn't easily generated and serialized from a hash in Perl, Python, Ruby, et al to JSON, because it has duplicate keys for "add".

It's cited at this page: http://wiki.apache.org/solr/UpdateJSON
Near the text: "Here's a simple example of adding more than one document at once:"

{
    "add": {"doc": {"id" : "TestDoc1", "title" : "test1"} },
    "add": {"doc": {"id" : "TestDoc2", "title" : "another test"} }
}'

Here's a better format that's analogous to the XML method of submission, and is easily serialized from a hash to JSON:

{
    "add": {
        "doc": [
            {"id" : "TestDoc1", "title" : "test1"},
            {"id" : "TestDoc2", "title" : "another test"},
        ],
    },
}

The original XML method:

<add>
    <doc>
       <field name="id">TestDoc1<field><field name="title">"test1"</field>
    </doc>
    <doc>
       <field name="id">TestDoc2<field><field name="title">"test2"</field></field>
    </doc>
</add>
