+The "string" type has been added as a new field type for metadata fields.
+
+In contrast to "text" fields, "string" fields are stored and indexed exactly as provided, without any text analysis or transformations.
+
+This field type is suitable for fields like IDs (e.g. ORCIDs) or enums, where exact matches are required when searching.
