Hello: Having looked with Google and found this pointer -
http://tex.stackexchange.com/questions/67848/can-pdf-search-find-words-with-ligatures-in-xelatex-documents However, if I extend the MWE there slightly, I can find "prefix", but not "quantitative". (My PDF reader is Evince on Ubuntu 12.04.) \documentclass{book} \usepackage{amsmath} \usepackage[MnSymbol]{mathspec} \setmathsfont(Digits,Latin,Greek)[Numbers={Lining,Proportional}]{Linux Libertine O} \setminwhitespace \setmathrm{Linux Biolinum O} \usepackage{xunicode} \defaultfontfeatures{Mapping=tex-text} \setmainfont{Linux Libertine O} \begin{document} Quantitative/Prefix. \end{document} Any help would be appreciated!
