I posted a variation of this code earlier, which scans a designated PDF for numeric values (listed in Column A of a worksheet) and returns a PDF with only pages that contain that numeric value. However, I am looking to modify this macro to search for Strings instead of just numbers (e.g. dog, cat, etc.). I tried changing some of the settings, but it did not work.

Below is the code that works for numeric values only. Any ideas where to change for alphabetic words? Thanks.
