查询字符串查询
curl -XPOST "http://localhost:9200/_search" -d'
{
    "query": {
        "query_string": {
            "query": "kill"
        }
    }
}'

curl -XPOST "http://localhost:9200/_search" -d'
{
    "query": {
        "query_string": {
            "query": "ford",
            "fields": ["title"]
        }
    }
}'

title这个字段的值里有单词ford

curl -XPOST "http://localhost:9200/_search" -d'
{
    "query": {
        "filtered": {
            "query": {
                "query_string": {
                    "query": "drama"
                }
            },
            "filter": {
                "term": { "year": 1962 }
            }
        }
    }
}'

no [query] registered for [filtered

解决办法: 过滤查询已被弃用，并在ES 5.0中删除。现在应该使用bool / must / filter查询。

curl -XPOST "http://localhost:9200/_search" -d'
{
    "query": {
        "bool": {
            "must": {
                "multi_match": {
                    "fields": [
                        "title"
                    ],
                    "query": "kill"
                }
            },
            "filter": {
                "terms": {
                    "year": [
                        1962
                    ]
                }
            }
        }
    }
