%% the current status of a list of documents so that you can determine if
%% they have been successfully indexed.
%%
%% You can also use the `BatchGetDocumentStatus' operation to check the

%% ingest your text and unstructured text into an index, add custom
%% attributes to the documents, and to attach an access control list to the
