I rebuilt the index. When the indexing was done, I deleted old index alias, and added the alias to the new index, as follows:-  
POST /\_aliases  
{  
"actions": [  
{ "remove": { "index": "dfse\_20151211", "alias": "dfse" }},  
{ "add": { "index": "dfse\_20151216", "alias": "dfse" }}  
]  
}

During the reindexing(making of the new index), documents were added to the old index.  
I tried getting the missing documents as below, but I get an error.

elasticdump --input=http://server:9200/dfse\_20151211 --output=http://server:9200/dfse\_20151216 --type=data --bulk=true --limit=500 --bulk-use-output-index-name=true --searchBody="{"query":{"bool":{"must":[{"range":{"asset.submitDate":{"gte":"2015-12-15","lte":"2015-12-17"}}}]}}}"

SyntaxError: Unexpected token q

What am I doing wrong?
