Can someone help with this Search GUI?

I was experimenting with Search GUI's and came up with this, now I was wondering if someone can tell me what I am doing wrong with it as to why it's only working if I type the full text? I want it to be visible if I type stuff like C and there's a frame named Cow.

Here's what I tried:

local frame = script.Parent.Parent.ScrollingFrame

script.Parent.Changed:connect(function()
	for _,v in pairs(frame:GetChildren()) do
		if string.find(script.Parent.Text,v.Name) then
			v.Visible = true
		else
			v.Visible = false
		end
	end
end)

How would I make it work if I typed stuff like "C"?

Any help appreciated.

Sorry I can't explain any better.

I noticed that my old answer was deleted for some reason. Never mind, I will take from Perci1's answer. I hadn't considered using string.match() for a search script before.

This is the hierarchy used in this script:

• ScreenGui
  • Frame
    • Frame (Called "Cow")
  • Script
  • TextBox (for searching)
  • TextButton ('search' button)

Script:

local searchText = "Search for your object here" -- text that you want your search box to display
local p =script.Parent
local f  = p.Frame
local children = f:GetChildren()
local text = p.Textbox
local button = p.TextButton
cow.Visible = false
text.Text = searchText

function search(txt)
	if txt ~= " " and txt ~= "" and txt ~= searchText then -- checks that the search is valid
		for _,v in pairs (children) do
			local name = v.Name:lower()
			text = txt:lower()
			local str = name:match(txt)
			if str then
				v.Visible = true
			end
		end
	else
		text.Text = "Invalid search"
	end
end

button.MouseButton1Down:connect(search(text.Text) -- fires when clicked

This should work. There was no rush this time, but I don't have access to Studio right now.

You can use string.match instead of string.find. It will return the first match found, or nil if there isn't a match.

local str = "Cow"
print( str:match("C") ) -->C
print( str:match("Hi") ) -->nil
