On the 'I'M LOOKING FOR' try searching for “mirage”, it is supposed to get 1 result. Same word in second search bar “I want to offer” suppose to get no result.
If you try to search for “compresseur” in first search instance it is supposed to return no result and if you try it in the second search instance you are supposed to get 1 result.
“Mirage” is in the title and content and “compresseur” is in custom field.
Hope it is clear!
