Perhaps use nested documents for your tag list?
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-aggregations-bucket-nested-aggregation.html
I don't think you can aggregate substrings in a single field since normal
aggregation is based on matches against the entire document. By having
nested (or parent child), now you have documents for each tag that you can
aggregate against.
