autocomplete - Elasticsearch自动完成其余的词

Question

我有一个用于 Elasticsearch 的自动完成功能的工作版本。但是，一个问题是，如果我搜索xbox360。我会得到xbox 360和xbox 1作为可能的建议。

我希望建议仅考虑在建议之前一直包含整个查询的建议。例如，如果我输入xbox 3，则 Elasticsearch 永远不要返回xbox 1，而只能返回xbox 360。

我的查询针对_suggestions端点运行。
我的配置如下。

{
    "mappings": {
        "query" : {
        "properties" : {
             "product" : { "type" : "string" },
             "name_suggest" : {
                 "type" :     "completion"
              }
         }
}

我认为您正在描述完成建议。如果是这种情况，可以使用以下示例:

PUT /mymusicsuggest
{
  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": 0
  },
  "mappings": {
    "album": {
      "properties": {
        "name": {
          "type": "string"
        },
        "suggest": {
          "type": "completion",
          "index_analyzer": "simple",
          "search_analyzer": "simple",
          "payloads": true
        }
      }
    }
  }
}

PUT /mymusicsuggest/album/1
{
    "name" : "Tori Amos - Little Earthquakes",
    "suggest" : {
        "input": [ "earthquakes", "little", "tori", "amos" ],
        "output": "Tori Amos - Little Earthquakes",
        "payload" : { "songs" : ["11861","11839","11849","11853","11841", "11847","11851","11845","11855","11843","11859","11857"] },
        "weight" : 10
    }
}
