# Can PDF search find words with ligatures in XeLaTeX-documents?

Is there some way allow PDF search to find words with ligatures? I use XeLaTeX.

\documentclass{book}
\begin{document}
Prefix.
\end{document}

In the resulting pdf file, searching for the word "Prefix" fails.

Note that this is searchable e.g. with SumatraPDF on Win7. I'm assuming you used Acrobat Reader, with which I can reproduce your problem. Good MWE! –  doncherry Aug 19 '12 at 21:01
