Looking for a WordPress theme for Postal Cards

Hi everybody !

Sorry for my poor english !!
I’m looking for a good theme in WordPress to make a website for vintage pictures (pictures and postal card).
I need to have, on the front website, more criterias to search a picture (date, town, name, surname, …).
I have a BDD (data) with about 10.000 pictures. So, it’s necessary that the engine search be very performant.
Could you help me to find one or more model themes for this project ?

Thanks for your reply !
Have a good day,
