It's not a bug: by default, "$" won't be counted as a word character. 
However, it is possible to change the set of characters that Scintilla 
treats as word-characters (and also what is treated as whitespace and 
punctuation).

At the moment, I don't think QScintilla provides a way to do this 
through the high-level api. (It is possible to re-implement the 
QSciLexer wordCharacters function, but I think this will only directly 
affect auto-completion). Instead, you could try setting the 
word-characters through the low-level api, i.e.:

     SendScintilla(SCI_SETWORDCHARS, characters)

Note that setting the word-characters in this way will change the 
behaviour of Scintilla in several ways, not just finding text. For 
instance, double-clicking a word to select it will include any new 
characters you have added.

For more info, see the Scintilla docs:

     http://www.scintilla.org/ScintillaDoc.html#SCI_SETWORDCHARS

And also the QsciScintillaBase docs:
