convert TIFF with underlying text to PDF?

[farmer]

Hi,
I want to produce text-searchable PDF files from image TIFF files with (hidden) data containing the textual content (seemingly with the location of each word in the image). I have tried using

convert ocrfile.tiff output.pdf

but the output.pdf file isn't text-searchable. Can I do it somehow?

I have just read that Microsoft introduced the text-searchable TIFFs, and it's not widely supported. So if ImageMagick doesn't support this, I have another question.
I do have access to the text contents, along with the location of each word in the image. Can I use ImageMagick to produce a text-searchable PDF using this information?
