That's the type of dynamic fields that Solr supports.

Solr needs to know the "type" of any given field.  To avoid having to
define all fields ahead of time, one can define a mapping between
field-name patters like  *_i to a type, so any field that ends with _i
not already in the schema will use the mapped type.
