Lua Jiddo's NPC System: FocusModule.messageMatcher(keywords, message)

[Cykotitan]

Could someone explain me how does this function work:

function FocusModule.messageMatcher(keywords, message)

Here's the entire function in LUA:

function FocusModule.messageMatcher(keywords, message)
		for i, word in pairs(keywords) do
			if(type(word) == 'string') then
				if string.find(message, word) and not string.find(message, '[%w+]' .. word) and not string.find(message, word .. '[%w+]') then
					return true
				end
			end
		end
		return false
	end

I've tried using it for different greeting keywords in a NPC script, this way; but it didn't work:

FocusModule.messageMatcher(FOCUS_GREETWORDS, "charach")

The NPC would ignore word 'charach' and would respond to default greet words (hello, hi, greetings)

Or.. Is there any other way to change the default greet keywords? Maybe by using a callback ;D?
Rep+ for helping me...
