Boosting

When you specify multiple query-clauses, you can specify the relative importance to a given clause by suffixing it with the ^ operator, followed by a number or by specifying the boost parameter with the number to boost the search.

Example

description:pool name:pool^5

The above syntax performs Match Queries for pool in both the name and description fields, but documents having the term in the name field score higher.

"query": {
    "disjuncts": [
         {
      "match": "glossop",
      "field": "city",
      "boost": 10
    },
         {
      "match": "glossop",
      "field": "title"
    }
  ]
}

The above syntax performs Match Queries for a city glossop in both the city and title fields, but documents having the term in the city field score higher.
