Question

我需要优先考虑以搜索字词开头的搜索结果。我用了“match_phrase_prefix”。我用了“match_phrase_prefix”。但是没有用。

详细说明：

查询

     GET /test/products/_search?pretty
        { 
          "query": {
            "match_phrase_prefix": {
             "title": "iphone 5c"
            }
          }
        }

结果

    "_score": 10.440153
    title": "Capa de Tpu para Iphone 5c Modelo Apple + Película"

"_score": 9.981493,
"title": "Capa Bumper Iphone 5C + Pelicula",

"_score": 8.610232
"title": "Pelicula Protetora para Iphone 5C Transparente"

"_score": 5.154923,
"title": "iPhone 5c Apple 8GB com Tela de 4”, iOS7, Câmera 8MP, Touch Screen, Wi-Fi, 3G/4G, GPS, MP3 e Bluetooth - Rosa"

"_score": 5.154923
"title": "iPhone 5c Apple 8GB com Tela de 4”, iOS7, Câmera 8MP, Touch Screen, Wi-Fi, 3G/4G, GPS, MP3 e Bluetooth - Branco"

"_score": 5.154923
"title": "iPhone 5c Apple 8GB com Tela de 4”, iOS7, Câmera 8MP, Touch Screen, Wi-Fi, 3G/4G, GPS, MP3 e Bluetooth - Preto"

映射

{{1}}
```

在这个例子中我需要的第一个结果是设备（Iphone 5c）

使用分析器导致标记化问题。请看下面的文档字段如何被标记化。

您需要使用关键字标记符。

curl -XGET 'localhost:9200/test/_analyze?analyzer=standard&pretty' -d 'Capa Bumper Iphone 5C' | grep token
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   532  100   511  100    21  32800   1347 --:--:-- --:--:-- --:--:-- 34066
  "tokens" : [ {
    "token" : "capa",
    "token" : "bumper",
    "token" : "iphone",
    "token" : "5c",
