For easy searching of documents, You can use the menu under Home - > Search.
Only the file names will be searched, not the content of the files.

There are technical or conceptual statements in some of the documents, which are not valid. We haven't changed the documents. Only in some of the documents we have edited, are signs "Warning" or "Alarm" marking these statements.
