PHPelasticsearch过滤查询字符串搜索

PHPelasticsearch过滤查询字符串搜索

实现此目的的一种方法是对字段使用muti_fields映射

description

。多字段中的一个字段不应进行分析。数据重新索引后，您可以使用简单的布尔查询来实现所需的目标：

例

创建索引：

put test{    "mappings": {        "data" : { "properties": {     "description" : {         "type": "string",          "fields": {  "raw" : {"type": "string","index": "not_analyzed"}          }     } }}    }}

索引数据：

put test/data/1 {    "description" : "a",    "test_id" : 10}put test/data/2{    "description" : "",    "test_id" : 10}put test/data/3{    "description" : "hello",    "test_id" : 10}put test/data/4{    "description": "a",    "test_id" : 20}

查询：

post test/data/_search{   "query": {      "filtered": {         "query": { "bool": {    "disable_coord": "true",    "should": [       {          "query_string": {  "fields": [     "description"  ],  "query": "a"          }       },       {          "constant_score": {  "filter": {     "term": {        "description.raw": ""     }  },  "boost": 0.2          }       },       {          "constant_score": {  "filter": {     "exists": {        "field": "description"     }  },  "boost": 0.1          }       }    ] }         },         "filter": { "terms": {    "test_id": [       10    ] }         }      }   }}

结果：

 "hits": [         { "_index": "test", "_type": "data", "_id": "1", "_score": 0.5113713, "_source": {    "description": "a",    "test_id": 10 }         },         { "_index": "test", "_type": "data", "_id": "2", "_score": 0.29277003, "_source": {    "description": "",    "test_id": 10 }         },         { "_index": "test", "_type": "data", "_id": "3", "_score": 0.097590014, "_source": {    "description": "hello",    "test_id": 10 }         }      ]

查询空字符串：

{   "query": {      "filtered": {         "query": { "bool": {    "disable_coord": "true",    "should": [       {          "query_string": {  "fields": [     "description"  ],  "query": ""          }       },       {          "constant_score": {  "filter": {     "term": {        "description.raw": ""     }  },  "boost": 0.2          }       },       {          "constant_score": {  "filter": {     "exists": {        "field": "description"     }  },  "boost": 0.1          }       }    ] }         },         "filter": { "terms": {    "test_id": [       10    ] }         }      }   }}

结果：

  "hits": [         { "_index": "test", "_type": "data", "_id": "2", "_score": 1.3416407, "_source": {    "description": "",    "test_id": 10 }         },         { "_index": "test", "_type": "data", "_id": "1", "_score": 0.44721356, "_source": {    "description": "a",    "test_id": 10 }         },         { "_index": "test", "_type": "data", "_id": "3", "_score": 0.44721356, "_source": {   "description": "hello",    "test_id": 10 }         }      ]
