What is the most optimized/shortest JSON structure I can use to submit multiple records to SOLR

Is this JSON legal to add documents to SOLR?

{
 "add": [{"doc": {"id" : "TestDoc1", "ti开发者_高级运维tle" : "test1"} },
         {"doc": {"id" : "TestDoc2", "title" : "another test"} },
         {"doc": {"id" : "TestDoc1", "title" : "test1"} },
         {"doc": {"id" : "TestDoc2", "title" : "another test"}}]
}

I am using SOLR 3.4 and submit using CURL from inside PHP. What should I see in the logs if this is not correct?

EDIT:This question was mistakenly understood as if I have a bug in the structure above (I did have a missing bracket) That was not the purpose. The question is a more generalized one, I edited the title to reflect this.

You are missing a } at the end there, are you not?

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

According to this site:

No, it is not valid JSON.

Here it is, cleaned up for you:

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

Use -

curl http://localhost:8983/solr/update/json -H 'Content-type:application/json' -d '
{
"add": {"doc": {"id" : "TestDoc1", "title" : "test1"} },
"add": {"doc": {"id" : "TestDoc2", "title" : "another test"} },
"add": {"doc": {"id" : "TestDoc1", "title" : "test1"} },
"add": {"doc": {"id" : "TestDoc2", "title" : "another test"}}
}'

OR

curl http://localhost:8983/solr/update/json -H 'Content-type:application/json' -d '
[
{"id" : "TestDoc1", "title" : "test1"},
{"id" : "TestDoc2", "title" : "another test"},
{"id" : "TestDoc1", "title" : "test1"},
{"id" : "TestDoc2", "title" : "another test"}
]'
