Full Search is preset and searches the albums from which you are authorized to download.
Searching as guest (logout!) works for all albums, but without download-permissions.
You have the option to narrow your search further by searching only specific albums.

Illustration using the search term: person – regardless of upper or lower case.

"quick-search" fast and effectively finds person, but non personal, persons.

"slow-search" also finds personal, impersonate, and persons etc.
It is slower and only recommended, if "quick-search" does not result in finding the desired pictures.

You can browse the located pictures or – regardless of which search you are using – you can add
more search terms, to narrow the search efficiently.
For example, you first search for ships, then you narrow the search with +port, and then possibly
with +Hamburg. There you go: All pictures of ships in the port of Hamburg were found! Or you
search: children+Luzern+school etc.
