Actually, if the text is in the same position on each page, you don't have to use the search feature to identify your redaction marks, you can just add the mark to the first page, then right-click on the mark, select Properties and set the "Redact area fill color" to your page background color (e.g. white). Then right-click on the redaction mark again and select to "Repeat mark across pages". You can then select which pages to copy the mark to. After you are done with that, make sure to apply your redaction selections.
