根据单词索引更改搜索顺序

您可以通过小写标准化术语位置来提高：

PUT sulphur{  "settings": {    "analysis": {      "normalizer": {        "keyword_lowercase": {          "type": "custom",          "filter": ["lowercase"]        }      }    }  },  "mappings": {    "properties": {      "text": {        "type": "text",        "fields": {          "keyword": { "type": "keyword", "normalizer": "keyword_lowercase"          }        }      }    }  }}POST sulphur/_doc{"text":"This medicine works like sulpher but does not contain sulpher at all."}POST sulphur/_doc{"text":"contains: sulpher Not recommended by most physicians"}POST sulphur/_doc{"text":"Sulpher This medicine contains sulpher and should be taken only after consultation with your doctor."}

然后

GET sulphur/_search{  "query": {    "bool": {      "must": [        {          "function_score": { "query": {   "match": {     "text": "sulpher"   } }, "script_score": {   "script": """     def pos = doc['text.keyword'].value.indexOf('sulpher');     return Math.exp((2.0/(pos+1)))   """ }, "boost_mode": "replace"          }        }      ]    }  }}

屈服
