The attached patch makes ligatures searchable in pdflatex output.
Tested with

  Windows XP
  Adobe Reader 9.0.0
  pdflatex 3.1415926-1.40.9 (MiKTeX 2.7)

and the following LaTeX packages:

Where you gave the additional information that you're using a teTeX
distribution shipped with Ubuntu.  The preferred TeX distribution for
unix-flavoured operating systems is TeX Live, nowadays.  A fresh

outdated and no longer maintained.  It might contain an older cmap.sty
package, that can break DVI compilation.

* nowadays, PDF provides better accessibility than PS,
* pdfTeX is known to produce very good (compatible) PDF code,
* hyper link, outline, PDF meta data, and XMP data support can be easily
added for PDF output,
* PDF size is around 260 kB smaller than PS size,
* ...
