Lightroom: Finding the Photos

I need to review some photos and need to show a dozen of the best images of that group. I have over 5,000 photos in that group. Going over the 5,000+ photos, again, would be very painful. I decided that I want to review, refine and reprocess the photos that I have already printed, for me that's a red label, or all the photos that I have already rated as a photograph with potential, for me that's a photograph with a rating of at least 1 star.

Lightroom is a front-end for an Oracle database called SQLite. Basically, I need to ask the following question:

Show me all the photos where
            the name of photo starts with "CHARLIE" AND
                   (the label is "RED" OR
                   the rating is at least "1 STAR")

The (the label is "RED" OR the rating is at least "1 Star") is called a sub-query. I want these only if the name of photograph starts with "CHARLIE".

Lightroom has the “magic” key: ALT/OPTION. When pressing the ALT/OPTION key and clicking on the +, you can get the sub-query. It shows up as indented on the Lightroom screen.

And I created the smart collection: charlie. Now, I only have to go through 185 photos.
