According to following article, we should use the smallest numeric datatype that fits the requirement. [https://www.elastic.co/guide/en/elasticsearch/reference/5.4/number.html#\_which\_type\_should\_i\_use](https://www.elastic.co/guide/en/elasticsearch/reference/5.4/number.html#_which_type_should_i_use) I want to understand in more detail that why and how search speed would get improved? Also, would that speed up aggregations as well? ---
