--- Comment #1 from V Stuart Foote <vstuart.foote at utsa.edu> ---
Regular Expression (LO's C++ ICU libs [1]) provide Wildcard matching--correctly
known as metacharacters and operators.

Prior to Eike's work on textsearch in bug 72196 for Excel interoperability,
simple Wildcard--"glob" syntax [2]--based text searches did not exist, and it
was convenient to refer to LibreOffice's pattern matching as "Wildcards"

It is now important to make a distinction as globbing ("*" "?") metacharacters
are present as operators in ICU Regex but with completely different function.

Given that we support both, I would agree assigning the "Regular Expression"
term for our legacy means of handling pattern matching is needed. While
relegating "wildcards" use to the specialized glob style searches (currently
only supported in Calc for interoperability with OOXML spreadsheets).
