Maybe? I don't use Pandoc directly (fantastic program, but I only use it thorugh Quarto and Rmarkdown), but something like `doxx document.docx --export text | grep "search term"` should work just like `cat`+`grep`, but with better table structure and no intermediate conversion needed like pandoc.
With pandoc you can do this I think
pandoc -t plain file.docx | grep "pattern"
Even better you can have pandoc output markdown.
Which almost looks like what this terminal program is doing ?
