-If a `date_of_birth` field mapped as a date were used, or an `age` field that

-`_all` only contains content from _string_ fields.
+The `date_of_birth` field in the above example is recognised as a `date` field

+`_all` field, however, treats all values as strings, so the date value is
+indexed as the three string terms: `"1970"`, `"24"`, `"10"`.
 
 It is important to note that the `_all` field combines the original values
 from each field as a string. It does not combine the _terms_ from each field.
