In Prioritizing Clauses, we explained how you could use the boost parameter at search time to give one query clause more importance than another. For instance:
GET /_search
{
"query": {
"bool": {
"should": [
{
"match": {
"title": {
"query": "quick brown fox",
"boost": 2 
}
}
},
{
"match": { 
"content": "quick brown fox"
}
}
]
}
}
}
