How Filtering In a Way That Distinguishes Between Uppercase and Lowercase Letters?

Hello everyone, I hope you're all doing well.

First of all: English is not my native language, and I am very, very, very bad with technology, though I can learn quickly if things are explained well. Please be kind.

I would like to perform searches/filtering that are case-sensitive (distinguishing between uppercase and lowercase letters). For example:

I want to search my music folder for files that contain the word "the" (all lowercase), "The" (only the first letter capitalized), or "THE" (all uppercase).

Is this possible in Mp3tag? Is there a "formula" or expression I can enter into the search/filter field?

Thanks in advance, and please, excuse any communication errors I may have made.

To filter for all the "The", try
Filter: %title% MATCHES "(?-i)The "
For the "the" try
Filter: %title% MATCHES "(?-i)the "

THANK YOU SO MUCH! It worked very well!

I made a few adjustments for my own personal use, and it ended up like this:

%title% MATCHES "(?-i) The "
%title% MATCHES "(?-i) the "
%title% MATCHES "(?-i) THE "

If it’s not too much trouble, could you explain this expression to me?

I understand the function of MATCHES, but what does (?-i) mean? I’d like to learn about it so I can use it in future expressions myself.

Thanks in advance!

MATCHES behaves like a regular expression.
(?-i) in regular expressions means: do not ignore case

Thank you so so so so so much!!!!!
