As already mentioned in this post the PhpWord library used in the Ingest app has a limitation: it does not support images.
Another limitation of this library is that it does not read bookmarks from the ‘docx’ document.
In order to hide the tags, created by the S&D operation which displaces the found text with another text when the app recreates the original document with the resulted data, we can use bookmarks because they are not visible to the user.
