How to search multiple names at once in Finder?

[vanko987]

I'm trying to create a search that will search for files with multiple file types. For example, I want to make a saved search where I can search for files that end in .mp4 and files that end in .mov. When I tried doing this though, nothing comes up. Am I doing something wrong? Is there a way to separate both filters so that Finder searches for both files that end in .mp4 and files that end in .mov?

Here's a screenshot of my finder window:

So, this is what I do:

- type anything in the search box. It doesn't matter what it is.
- In the area below, where is says "Search this Mac" etc., I click the + next to "Save" on the right.
- That shows a new band "Kind is Any". Hold the option key and click the + on the right.
- This opens an "Any of the following are true" and then you can create a separate search for "Name matches .mp4". click + to the right of that and search "Name matches .mov"
- Then delete the anything that you typed in the search box in step one (just put the cursor there and backspace until there is nothing there.)
