prefix

根据前缀去查询

POST     /shop/_doc/_search
{
    "query": {
        "prefix": {
            "desc": "imo"
        }
    }
}

• head 可视化

  fuzzy

  模糊搜索，并不是指的sql的模糊搜索，而是用户在进行搜索的时候的打字错误现象，搜索引擎会自动纠正，然后尝试匹配索引库中的数据。 ```shell POST /shop/_doc/_search { “query”: { “fuzzy”: {

  "desc": "imoov.coom"

  } } }

  或多字段搜索

  { “query”: { “multi_match”: {

  "fields": [ "desc", "nickname"],
  "query": "imcoc supor",
  "fuzziness": "AUTO"

  } } }

{ “query”: { “multi_match”: { “fields”: [ “desc”, “nickname”], “query”: “演说”, “fuzziness”: “1” } } }
