Term filter: integer vs string?

Elastic Stack Elasticsearch
1

I saw that in the term filter doc page
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-terms-filter.html
it shows an example

curl -XPUT localhost:9200/tweets/tweet/1 -d '{
"user" : "2"
}'

here the user id "2" is put as string. In other databases generally one
would use an integer field to represent such id. I wonder is there any
difference in performance (mainly concerning term filter) between string vs
integer?

The way the term filter is executed is the same for strings and integers so
I wouldn't expect any performance difference here.
