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!– doncherryAug 19, 2012 at 21:01

Add \usepackage{fontspec}. This actually loads the package fontenc, which would solve your problem for pdfLaTeX.
As a result, the ec fonts are loaded instead of the standard Computer Modern fonts, as Ulrike remarked in the comments. For other fonts, other solutions might apply; this answer addresses a standard setup as seen in the OP's MWE.

5Your solution works because with
fontspecyou are using a different font which uses correct glyph names and so allow the pdf reader to "understand" the ligature.\usepackage[T1]{fontenc}(which switches from the cm fonts to the ec fonts),\usepackage{lmodern}or\usepackage{times}work too. Aug 20, 2012 at 8:37 -
@Ulrike - Thanks for your clue in this comment! fontspec doesn't help for fonts without proper glyph names, e.g. Cambria. I switched to LibertineOTF and all is well.– srkingAug 20, 2012 at 22:52

I have a similar problem. After adding '\usepackage{fontspec}' to the minimal example the word "prefix" becames searchable, however after adding '\setmainfont[Path=Fonts/,Extension=.ttf,BoldFont=FrutigerLTCom-Bold,ItalicFont=FrutigerLTCom-Italic,BoldItalicFont=FrutigerLTCom-BoldItalic]{FrutigerLTCom-Light}' the problem returns.– MikMay 3, 2018 at 14:37

By the way, the document with the Frutiger font worked for years until I shortly updated my MikTeX.– MikMay 3, 2018 at 16:18
