in reply to searching polygons not merged

How can I generate an example polygon collection? (i.e., what does "10000 EA" mean?)

I wouldn't be surprised if searching for overlapping polygons in a database of indexed polygons would be fast. If you had an example of "not that good performance and stupid way", I could see if a database search would indeed be better and "less stupid".
