ElasticSearch match multiple fields with different values
As you may know elasticsearch match query returns result based on a relevance score. You can try to use term query instead of match for an exact term match. Also I guess your bool query structure must be like :
bool: { must: [ { match: { country_id: "1" }}, {match: { region_id: "2" }}, {match: { appellation_id: "34" }}, {match: { searchable: search }} ] }
