Agro-ecology: an additional weapon to fight climate change
The search requires words of at least 3 letters and does not differentiate between upper and lower case.
Writing two or more words (e.g. Rome Naples), the result shows images that contain either of the indicated words.
Using the “+” tool in front of two or more words (e.g. +Rome +Naples), the result shows images that contain both words.
Using the “-” tool in front of a word (e.g. +Rome -Naples), the result shows images that contain the word Rome but not the word Naples.
If you don’t know the exact word to search, you can use the “*” tool at the beginning or end of that word or in the middle (for example, if you write Rom*, the result shows images that contain the words Roma, Rome, Romulus etc.; if you write Rom*a the result shows images that contain the words Romagna, Romania, Romina etc.; if you write *oma, the result shows images that contain the words Roma, Romania, Toma, Boma, etc.).
