FWIW, I would agree with this assessment.  The regex requirements for 
this are simpler than full JavaRE (for example), because we're not doing 
replacements, which is where a lot of regex complexity comes in - so 
grouping and forward/backwards references aren't needed.

But a switch to go between simple wildcard settings and full regex would 
be nice.   Similarly, tools that would enable/disable regex flags 
(another area that can get confusing for novices) would be good - so case 
sensitivity can be enabled/disabled using a checkbox rather than having 
to remember to prepend (?i) to the expression.

But the essentials of regex are useful:

"." = a single character (or nothing)
"*" = repeat the previous character any number of times
"[A-Z]" and other ranges = ranges of characters.
"^" = start of line
"$" = end of line

And of course "\" to escape special characters used in the above. :)
