ES設置字段搜索權重——Query-Time Boosting

Query-Time Boosting

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" } } ] } } }

	The title query clause is twice as important as the content query clause, because it has been boosted by a factor of 2.
	A query clause without a boost value has a neutral boost of 1.
