Bonjour 
Please don't post images of text as they are hardly readable and not searchable.
Instead paste the text and format it with </> icon. Check the preview window.
Could you provide a full recreation script as described in About the Elasticsearch category. It will help to better understand what you are doing. Please, try to keep the example as simple as possible.
A full reproduction script will help readers to understand, reproduce and if needed fix your problem. It will also most likely help to get a faster answer.
Also note that you have this forum in french as well if you are not confortable with english (but you look confortable IMO): #in-your-native-tongue:discussions-en-francais
