            }
        }
    }
}

}

here is the nest query:

QueryContainer queryContainer = new BoolQuery
        {
            Should = new QueryContainer[ ] {
                new QueryStringQuery {   Query = query,DefaultOperator=Operator.Or, Fields = SearchFields.fields.ToArray()},
            },
        };

@Abderrahmane_Saadoun, please can you format your code, using </> icon as explained in this guide. It will make your post more readable.

Or use markdown style like:

```

```

This is the icon to use if you are not using markdown format:

There's a live preview panel for you to see how the formatting looks before posting.

Hello thanks for your reply

I have formated my text as asked.

Your question does not seem to include all the details to be able to answer it. For example,

  • What is SearchFields?
  • Which field(s) are you trying to target for an exact match?

Would you be able to provide a full, minimal, reproducible example that demonstrates the problem?

hello thanks again.

Here is the searchFields :

{
 "formationContinues.titre^17",
 "formationContinues.organisme^16",
 "formationContinues.pays.nom^23",
}

And i want to target all of the searchFields to show exact value first

For example if i search for Salas, i get Sales,salé......... before the name Salas because the boost value is bigger than the others.
