I would like to partial update documents per query.  
Seems this is not implemented in ES yet, the only way is to use the update  
by query plug-in.

I checked the example in above site, and know how to update numeric field  
by script:

curl -XPOST 'localhost:9200/twitter/\_update\_by\_query' -d '{ "query" : { "term" : { "message" : "you" } }, "script" : "ctx.\_source.likes += 1"}'

But I still have no idea how to update a text field by query. Example, if I  
have a following doc:  
{"title":"hello", "text":"my text"}

I like something like this:  
{  
"query" : {  
"match" : {  
"title" : "hello"  
}  
},  
"doc" : {  
"text" :"new text"  
}  
}

How can I do?
