+-- | A string that represents the name of an index field. CloudSearch supports
+-- regular index fields as well as dynamic fields. A dynamic field's name
+-- defines a pattern that begins or ends with a wildcard. Any document fields
+-- that don't map to a regular index field but do match a dynamic field's
+-- pattern are configured with the dynamic field's indexing options.

+-- Regular field names begin with a letter and can contain the following
+-- characters: a-z (lowercase), 0-9, and _ (underscore). Dynamic field names
+-- must begin or end with a wildcard (*). The wildcard can also be the only
+-- character in a dynamic field name. Multiple wildcards, and wildcards embedded
+-- within a string are not supported.
+--
+-- The name 'score' is reserved and cannot be used as a field name. To reference
+-- a document's ID, you can use the name '_id'.
