+command 'report' with options '--with-ldp' and '--with-filetypes' should be used with care because the running time
+      increases from O(n) to O(n²) if one option is used
+      or increases to O(n³) if both options used
+      (with n => count of AIPs)

+ensure the ElasticSearch server allows to return >10.000 results if your archive is large, especially if you use
+file-specific options like '--pronom-id' or '--with-filetypes'.
