[SOLVED] How can I 'match whole word only'?

Most audios that have been amplified have 'loud' in the title. I have a boombox and I want to prevent these audios being played. I have made it so that if it finds 'loud' in the title or description then it gets refused. The ROBLOX studio search (CTRL+F) lets you search for a whole word only so it can't be included in a word, as 'loud' is in 'cloud'. I can't think of a way to do this, my current code searches for the word, but not just the word, so these are the results when searching for loud:

'cloud' --> true
'cloud.' --> true
'louder' --> true
'louder.' --> true
'loud' --> true
'loud.' --> true

But these are the results I want:

'cloud' --> false
'cloud.' --> false
'louder' --> false
'louder.' --> false
'loud' --> true
'loud.' --> true

I can't work out a method for achieving this, I hope you can help!

You should 1st look at Character Classes as you will need to understand how string patterns work.

The main problem is knowing when a new word has started which is why cloud would match.

The pattern %f[%l]loud%f[%L]%.? this will look for the whole word loud in lower case %l I have also added '%.?% which will look for 0 or one match of the literal '.'

My testing:-

local test = {
    'loud', 'loud.', 'Loud', 'Loud.',
    ' loud', ' loud.', ' Loud', ' Loud.',
    ' loud ', ' loud. ', ' Loud ', ' Loud. ',
    'cloud', 'a loud', 'very'
}

local pattern = '%f[%l]loud%f[%L]%.?'

for i, str in pairs(test) do
    local match = str:match(pattern)
    if match then
        print('String found index', i,'String ', str, 'Res', match)
    else 
        print('Did not find', str)
    end
end

I hope this helps.

Hey, this is gonna be a short answer because, I literally have like 1 minute but, here are the scripts that I managed to come up with: If you don't understand anything please post it in the comment below.

-- Won't print anything
local matching = "loud"
local name = "cloud"

for w in string.gmatch(name, matching) do
if #w == #name then
print(w)
end
end

-- Will print "loud"
local matching = "loud"
local name = "loud"

for w in string.gmatch(name, matching) do
if #w == #name then
print(w)
end
end

Thank you for your time and I am sorry this is a really messy answer but, it should be helpful. Don't forget if you don't understand anything, comment below.
