RegEx pattern operators:
                ^               Anchor start
                $               Anchor tail
                [ ]             Character range (case-insensitive)
                .               Matches any 1 character
                +               Matches 1 or more of the preceeding elements
                *               Matches 0 or more of the preceeding elements
                \               Escapes regex specials

It is unknown if {Z:H} works in a simple search.
It is unknown if [^a-z] works in RegEx.
It is unlikely that case-sensitive (^) and word match (~) work in RegEx.
Basics and RegEx work in both simple and free form searches.
