RegEx, AHK, MS Word

[pom]

This is Haystack:

higher temperature
random text
higher random text random text temperature

This is NeedleRegEx: hig.{1,6}tem, which finds the following (red) pattern:

higher temperature
random text
higher random text random text temperature

However, when I go to MS Word's Advanced Find, check "use wildcards" checkbox and type hig?{1,6}tem , which is compatible with hig.{1,6}tem NeedleRegEx, it finds the following (red) patterns:

higher temperature
random text
higher random text random text temperature

Why does it find higher random text random text tem pattern? If I understand this correctly, it shouldn't find it because there are much more than 6 characters between hig and tem. But it finds it… Why? I don't understand am I doing something wrong or is it a bug in MS Word?
Thanks.

[TLM]

While wild card search is similar to RegEx, its definitely not the same.
Looks like the `Any single character` or ? token is being repeated in this case ( not sure why )..
Also wildcards deal with spaces much differently than RegEx.

After some messing around I've come to realize you can't use space as a `special character`..
try: hig[a-z]{1,6} tem

Yes...

try: hig[a-z]{1,6} tem

That worked well in this situation. Thank you!
