[Tex/LaTex] How to make the exported PDF searchable

exportlyxpdf

I export an English document to PDF using pdflatex on LyX. The resulting PDF is not searchable (although all the external embedded PDFs that I included as graphics are searchable).

Also, when I select and copy text, it appears as "✇❤✐❝❤ ✐s ❞❡✜♥❡❞" when I paste it.

How do I make my generated PDF searchable?

Under "Use LaTeX font encoding:" it says "T1" and the LyX file is:

#LyX 2.0 created this file. For more info see http://www.lyx.org/

Best Answer

Firstly, you're essentially making the embedded pdfs pictures, hence why they are not searchable.

What you'll want to do is use something like pdfpages to include your files.

For example:

\usepackage{pdfpages}
\includepdf[pages={-}]{yourfile.pdf}

This will include all the pages in the document (as the range character "-" has no beginning or end value). If you want to put only a few pages into your new pdf, then you can use pages={1,2,9} for example.
