Text Search problem

Hi,
I have a problem (or is a limitation I don't know?) in Find Text into my PDFs. It seems that works when font is Times New Roman (or similar) and not works (after a long time it responds with a "not found" alert, or it blocks the program) when font is Arial (or similar). There is something I forgot to setup, or is a known bug?
Thank you!

Hi,
One possibility is that one PDF file has searchable text in it while the other only has a graphical representation (an image) of the text.

It depends on what settings the person had on making the PDF file. For the text search to function, the PDF file needs to have searchable text. It may be just a coincidence that one file works (and has times roman font) and one file doesn't (arial).

Thank you tony_w,
I found the solution after reading your answer. It was caused by PDFPrinter, a virtual PDF printer based on Ghostscript. The problem was that PDFPrinter was mapped over GNU GhostScript release 7.08, that, for some fonts, generated non-searchable text (PDFs are just for printing); I noted that also Acrobat was unable to find text in Arial-like fonts in the same PDFs. Using AFPL GhostScript release 8.13, generated PDF files are completely searchable, and all works well.
Maybe this can be useful for other people.
