ElasticSearch query relevance - elasticsearch

Question

I would like to find a product with the search priority : pickRef, name, synonym (it's an array) and the others after. I don"t succeed to have a working query.. I have to boost synonym with "50" in order to have the product in top 8 results...
The aim of my query is to make an autocompletion search with fuzzy (to avoid mispelling)
I have a product with the synonym "caca" When I want to search "caca" ES return every coca products. but not the product with the synonym "caca". However, the term "caca" must be the first result beceause it match perfectly with synonym field and coca products must come after (due to fuzzy parameter)
There is my index :

PS : I know the example is not perfect but I don't have a better one...

Answer 1

do you try to sort by _score?
{
"index": "product",
"size": 8,
"body": {
"query": {
.

.
},
"sort": [
{
"_score": {
"order": "desc"
}
}
]
}
}
