I have an index called "shipments" and it has a STA\_CD. I would like to perform an update using CURL to update all documents with STA\_CD = "OH" to STA\_CD="FL". I'm having a lot of problems with the syntax.  
Here's what I'm starting with but I'm not getting any matches:

curl -X POST "localhost:9200/shipments/\_update\_by\_query" -H 'Content-Type: application/json' -d'  
{  
"query":{  
"term":{  
"STO\_STA\_CD":"OH"  
}  
},  
"script":"ctx.\_source.STO\_STA\_CD = 'AK'"  
}  
'
