所以我的方案是在我的应用程序中有一个内联搜索,就像我们在Udemy网站的标题栏上有一个内联搜索,用户可以在其中输入多个单词。现在,我想使用用户输入的多字搜索文本来查询多个字段。

我要查询的多个字段具有以下映射

_mapping

{
    "category": {
        "type": "keyword"
    },
    "designers": {
        "type": "nested",
        "properties": {
            "name": {
                "type": "keyword"
            }
        }
    },
    "story": {
        "type": "text"
    },
    "foundryName": {
        "type": "text",
    }
}

我的问题是如何进行多字搜索,例如“designerFirstName1 category1 foundryName1”,并获得匹配文档中包含来自我搜索的任何一个多字段中的每个字的结果< strong>当我继续添加更多单词时,结果集应该会减少。

查询

{
    "query": {
        "bool": {
            "should": [
                {
                    "nested": {
                        "path": "designers",
                        "query": {
                            "match": {
                                "designers.name": {
                                    "query": "designerFirstName1 category1 foundryName1",
                                    "fuzziness": "auto"
                                }
                            }
                        }
                    }
                },
                {
                    "multi_match": {
                        "query": "designerFirstName1 category1 foundryName1",
                        "type": "cross_fields",
                        "fields": [
                            "story",
                            "foundryName",
                            "category",
                        ]
                    }
                }
            ],
            "minimum_should_match": 1
        }
    }
}

预期的结果是这种文档应该更高,然后当我们向下时结果开始没有任何一个字段中的所有多字(如下所示)

{
    "category": [
        "category1",
        "category2"
    ],
    "designers": [
        {
            "name": "designerFirstName1 designerLastName1"
        },
        {
            "name": "designerFirstName2 designerLastName2"
        }
    ],
    "story": "Sphinx of black quartz, judge my vow! Sex-charged fop blew my junk TV quiz.",
    "foundryName": "foundryName1"
},
{
    "category": [
        "category2",
        "category3"
    ],
    "designers": [
        {
            "name": "designerFirstName1 designerLastName1"
        },
        {
            "name": "designerFirstName2 designerLastName2"
        }
    ],
    "story": "Sphinx of black quartz, judge my vow! Sex-charged fop blew my junk TV quiz.",
    "foundryName": "foundryName1"
},
{
    "category": [
        "category1",
        "category3"
    ],
    "designers": [
        {
            "name": "designerFirstName3 designerLastName1"
        },
        {
            "name": "designerFirstName2 designerLastName2"
        }
    ],
    "story": "Sphinx of black quartz, judge my vow! Sex-charged fop blew my junk TV quiz.",
    "foundryName": "foundryName1"
},
{
    "category": [
        "category2",
        "category3"
    ],
    "designers": [
        {
            "name": "designerFirstName3 designerLastName1" /*changed here comparing with the above document*/
        },
        {
            "name": "designerFirstName2 designerLastName2"
        }
    ],
    "story": "Sphinx of black quartz, judge my vow! Sex-charged fop blew my junk TV quiz.",
    "foundryName": "foundryName1"
},
