</div>

eg.  
{  
"script": {  
"source": "if (ctx.\_source.supplier.contains(params.supplier)) { ctx.\_source.supplier.remove(ctx.\_source.supplier.indexOfparams.supplier) ;ctx.\_source.supplier.add(params.supplier) }",  
"lang": "painless",  
"params": {  
"supplier": {  
"gysmc": "test",  
"kcl": 53454  
}  
}  
}  
}

A syntax error occurred when I wrote this in script,Is there a relevant example?
