 == Field data types
 
-Elasticsearch supports a number of different data types for the fields in a
-document:
+Each field has a _field data type_, or _field type_. This type indicates the
+kind of data the field contains, such as strings or boolean values, and its
+intended use. For example, you can index strings to both `text` and `keyword`
+fields. However, `text` field values are <<analysis,analyzed>> for full-text
+search while `keyword` strings are left as-is for filtering and sorting.
+
+Field types are grouped by _family_. Types in the same family support the same
+search functionality but may have different space usage or performance
+characteristics.
+
+Currently, the only type family is `keyword`, which consists of the `keyword`,
+`constant_keyword`, and `wildcard` field types. Other type families have only a
+single field type. For example, the `boolean` type family consists of one field
+type: `boolean`.
