1. query with version field

> according to elasticsearch document, once a document is modified, filed of 'version' will automatically increased by 1.  
> **question is** : how can I get all items which version field is greater than 1, any example dsl statement or document ?

1. append data to exists field when \_id exists

> If my data structure is something like this(let's call this log 'log\_old'):
> 
> > {"\_id":123, "logs":[{....}, {....}]}
> 
> when there is a new item with same id(let's call this new log 'log\_new'),I just want something like this
> 
> > log\_old.logs.append(log\_new.logs)
> 
> new log's specific field is appended to old log.  
> I found 'script' keyword, accroding to document's exapmles,I assume 'script' can olny do some mathematical operation(like add some value), or simple string operation(like string splice).  
> **question is** :how can I append some data to an array object when item exists ?

Not sure about 1.  
But you cannot do 2, if you update a document it'll overwrite the existing array
