Version: (using KDE 4.1.4)

Here are two words: fire, fire.
They are identical, except that the first one contains a ligature
bringing the f and the i together. The second one has no ligature. The
first is the standard in proper typesetting, and it is the default
output of LaTeX.
If I search for "fire" in Okular, the word will not be found, because
Okular doesn't understand the ligature. By way of comparison, Adobe
Reader for Linux does understand the ligature, and finds the word.
This can lead to great frustration.
I imagine that this applies to all documents in Okular, rather than
being specific to the PDF backend. There are a handful of other common
ligatures that this applies to (see
http://en.wikipedia.org/wiki/Typographic_ligature).

okular 0.8.2.
ubuntu 9.04
kde 4.2.2
If you search for 'config' on the PDF mentioned in Jaruh's link, the
first result returned will be on page 7. However, the first result
returned should be on the bottom of page 3, where 'configurations' is
written.
I made sure the 'use case sensitive' and 'from current page' options
were NOT enabled.

This always happens with pdf files produced by pdflatex as it makes use
of ligatures.

Just for the record, if anyone things that patch is useful, it is not.
Also, for the record, Adobe Reader 9.3 is not able to find the word
"configurations" in document from comment #1

I too can confirm this bug for okular 0.9.5, kubuntu 9.10 and kde 4.3.5.
Also, the copy function should separate ligatures, like Evince does.

Confirming this bug still exists in KDE 4.4.1.
Also, this was previously reported for kpdf as Bug 103621, so more

reply to comment 7:
i’m sorry my “patch” isn’t useful, but at least it would be a way to quickly circumvent the problem until a better solution is found. and “program x does it equally wrong” is no excuse if we can do it better.
