在查询字符串中突出显示通配符的术语问题

Question

我们正在使用Elasticsearch版本5.4.3

  

1：我们使用以下设置和映射创建了索引。

PUT http://localhost:9200/essearch
{ 
"mappings": {
    "object": {
        "_all": {
            "enabled": false

                        "all",
                        "under",
                        "very",
                        "well"]
                }
            },
            "analyzer": {
                "content_phonetic": {
                    "filter": [
                        "content_phonetic"
                    ],
                    "char_filter": [
                        "CharFilters"
                    ],
                    "type": "custom",
                    "tokenizer": "standard"
                },
                "content_stemming": {
                    "filter": [
                        "lowercase",
                        "porter_stem"
                    ],
                    "char_filter": [

                    "filter": [

                        "StopWords"
                    ],
                    "char_filter": [
                        "CharFilters"

                        "_ => ' '",
                        ": => ' '"
                    ]
                }
            }
        },
        "number_of_replicas": "0"
    }
}}

  

2：将文档编入索引

http://localhost:9200/essearch/object/1
{ "content" : "beginning thirty days after the anticipated COD. 
         Buyer shall be responsible for all natural gas and electrical imbalance charges.
         All prices shall be at the Reference Conditions.
         Buyer’s performance of its obligations under the ECSA with a form of guarantee in an amount. Seller shall assign its rights under said requests to Buyer.  Buyer shall have full dispatch rights subject to operational parameters  (including ramp rates. buyer said to me..."   }

  

3：执行了突出显示查询

 http://localhost:9200/essearch/_search
  {
   "highlight": {
      "pre_tags": [ "<term0 style='background-color:Lime'>", "<term1 style='background-color:Chocolate'>", "<term2 style='background-color:Pink'>"
   ],"post_tags": [ "</term0>", "</term1>", "</term2>" ],
  "encoder": "html",
   "fields": { "content": { "fragment_size": 50, "number_of_fragments": 0, 
   "type": "fvh" } } },
    "_source": false,
   "query": {
   "bool": {
       "must": [
{
  "query_string": {
    "query": "(a*) OR (said) OR (buyer)",
    "default_field": "content"}} ],
     "filter": [
{
  "ids": {
    "values": [ "1" ] } } ] } } }

  

4：突出显示查询输出

{
"took": 0,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"failed": 0
 },
"hits": {
"total": 1,
"max_score": 0,
"hits": [
  {
    "_index": "hi3",
    "_type": "object",
    "_id": "1",
    "_score": 0,
    "highlight": {
      "content": [
        "beginning thirty days after the <term0 style='background-color:red'>anticipated</term0> COD.<term2 style='background-color:Pink'>Buyer</term2> shall be responsible for all natural gas <term2 style='background-color:Pink'>and</term2> electrical imbalance charges. All prices shall be <term2 style='background-color:Pink'>at</term2> the Reference Conditions. Buyer’s performance of its obligations under the ECSA with a form of guarantee in <term1 style='background-color:yellow'>an</term1> <term0 style='background-color:red'>amount</term0>. Seller shall <term1 style='background-color:yellow'>assign</term1> its rights under <term2 style='background-color:Pink'>said</term2> requests to <term2 style='background-color:Pink'>Buyer</term2>.  <term2 style='background-color:Pink'>Buyer</term2> shall have full dispatch rights subject to operational parameters  (including ramp rates. <term2 style='background-color:Pink'>buyer</term2> <term2 style='background-color:Pink'>said</term2> to me..."
      ]
    }
  }
]
}
 }

在上述查询中，应将标签“ term0”应用于所有以“ a”开头的单词，将标签“ term1”应用于单词“ said”，将标签“ term2”应用于单词“ buyer”，但这不是这种情况。我在某处读到fvh可以按顺序在查询中应用多个标签，而这在这里不起作用。
