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.
{
"field":"city", "match": "glossop", "boost":5`, `field":"title", "match": "glossop"}
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.
