Basic Spotlight Search

I couldn’t find this in any of the postings but it seems to me it should be very simple. I want to do a spotlight search from an appleScript for a particular folder. Leaving the folder part out for now, I thought I could do this but it doesn’t work:

tell application “Finder”
find “the text you want”
end tell

All I get is a blank spotlight window. How do I do it and how can I search a specific folder?

Thanks in advance.
