Querying for documents which do not contain an element in an array field

Elastic Stack Elasticsearch
1

Suppose I have a document with a "tags" field which is an array (just
as here http://www.elasticsearch.org/guide/reference/mapping/array-type.html)

Is it possible to query for documents do not contain a given tag?

Thanks,
Adam
