-- | The condition used for the target document attribute or metadata field
-- when ingesting documents into Amazon Kendra. You use this with
-- <https://docs.aws.amazon.com/kendra/latest/dg/API_DocumentAttributeTarget.html DocumentAttributeTarget to apply the condition>.
--
-- For example, you can create the \'Department\' target field and have it
-- prefill department names associated with the documents based on
-- information in the \'Source_URI\' field. Set the condition that if the
-- \'Source_URI\' field contains \'financial\' in its URI value, then
-- prefill the target field \'Department\' with the target value
-- \'Finance\' for the document.
--
-- Amazon Kendra cannot create a target field if it has not already been
-- created as an index field. After you create your index field, you can
-- create a document metadata field using @DocumentAttributeTarget@. Amazon
-- Kendra then will map your newly created metadata field to your index
-- field.
--
-- /See:/ 'newDocumentAttributeCondition' smart constructor.
