SUMMARY
The Find function misses target occurrences that wrap to the next line of text.

STEPS TO REPRODUCE
1. Control-f to initiate Find. Type in "one-third".  The "one-third" in mid
sentence is found.  The "one-third" in "not less than one-[carriage return]
third that of the larger conductor" is not.  This also does not find other
phrases used to describe numerical fractions.  For example, two-thirds,
three-quarters, etc.
2. Copy "when not[carriage return]
part of the wiring".  Control-f to initiate Find.  Paste string into Find. 
Press Next.  Text is found.
Control-f to Find.  Type "when not part of the wiring" in Find.  Press Next. 
Text is not found.  Okular appears to be miss any text string that is typed in
if it wraps from one line to the next.
3. 

OBSERVED RESULT
Misses occurrences of target string that wrap to next line of text.

EXPECTED RESULT
Should find target text strings that wrap from one line to the next.
