I want to have some flexibility but on the content categorie slugname i want to search exactly the word for example arts-de-la-rue but when i make a search i found result with categorie = arts or categorie = lecture, i don't understand the problem :( If somebody can help me :)

Answer 1

You have to setup your mapping for that field

your field: { type: "string", index: "not_analyzed" }

And just to be sure destroy the type and populate it again.
