<cfset sTmp=REReplaceNoCase(qResults.Slug,'^[^a-z0-9_]*([a-z0-9_])','\1'>
to get rid of all leading characters you do not want, and then use sTmp for you Find.
Just a few remarks:
'^[^a-z0-9_]*([a-z0-9_])' means
First ^- Start at the start of the string only
[] one of those inside, with the second ^ - one of those NOT inside
* - repeated 0 to x times
() take everything inside and remember it - for a back reference \1 later
The () has to be used to make sure that all leading whitespace is removed (ad consequently, you need a back reference later)
You might want to experiment using a different collection of excluded/included chars. There is for example \s for whitespace, \S for non-whitespace, but my experiments with those CF-specific character class definitions were never too lucky, so I prefer enumerating the characters I want/don't want.
