Hey @tomak, where are you seeing the question mark? When you insert strings into Elasticsearch by default it stores a "text" and a "keyword" field for your string, https://www.elastic.co/blog/strings-are-dead-long-live-strings does a good job explaining why. You'll be able to do a full-text search against the "text" field and you can do terms aggregations/etc. against the "keyword" field.
