We propose you two types of research.
The Free Search at the top right
This search is guided, that is to say that typing the first 3 letters of a word we propose you a list from a dropdown menu.
The Research with the thesaurus, on your left
this search allows you to enter a keyword in the field below and by clicking OK, the thesaurus unfolds.
Click again on that word and the pictures appear.
You can also unfold the thesaurus by clicking the little cross in front of each word. This will give you the environment of each keyword.
Warning ! You must absolutely enter the words in the singular !
