Regex - why does this work? (problem with wildcard usage)

bsuk

I'm trying to understand why this is returning a result. Am I missing something with my understanding of regular expression, or is it a DataTables setting/browser issue that I'm not aware of?

I would expect Integ* to return a result, but it seems to be ignoring the final character?

Yep, that's behaving as expected - see here - you've got to trust Wikipedia

• The asterisk indicates zero or more occurrences of the preceding element. For example, ab*c matches "ac", "abc", "abbc", "abbbc", and so on.
