Search works with keywords but it finds only consecutive words. It dosn't find if these keywords are in other oreder.
I have peoples names as keywords like "Firstname1 Lastname1, Firstname2 Lastname2""
It dosn't find the photo if I search for "Lastname1 Firstname1" or "Lastname1 Lastname2"
This feature does not appear to have been implemented yet. I don't seem to be able to do an "and" search. Find name1 and name2. It searches each word independently. I am writing this, just to bump this suggestion.
Turtle 6 will have this feature, just like Photoblogger does. term1 term2 - finds all images with either term1 OR term2 term1 and term2 - find all images that contain both term1 AND term2 "term1 term2" - finds only the images containing term1 term2 next to each other
