+Sparse, or serialized fields do not live as a column in the database table.
+Instead, their values are stored in JSON arrays in a separate field. As a
+result, these fields cannot be searched or sorted by.
+
+If such a sparse field is created as 'manual', this module can unserialize
+the field. Its field definition and values will then be migrated to a
+proper database column. A real life use case where you encounter many
+of such fields is the Magento-OpenERP connector.
+
+For technical reasons, many2many and one2many fields are not supported.
