我们正在使用ElasticSearch中的过滤器,我们需要逐字逐句完整地突出显示:

例如,我们有下一个搜索:

curl -X GET "localhost:9200/my-index/_search" -H 'Content-Type: application/json' -d'
{
    "query" : {
        "percolate" : {
            "field": "query",
            "document" : {
                "title" : "A new bonsai tree in the office and jungle. The enojen tree in a kerojen."
            }
        }
    },
    "highlight": {
      "fields": {
        "title": {}
      }
    }
}
'

然后我们得到下一个输出:

{  
   "took":12,
   "timed_out":false,
   "_shards":{  
      "total":5,
      "successful":5,
      "skipped":0,
      "failed":0
   },
   "hits":{  
      "total":45,
      "max_score":2.1576157,
      "hits":[  
         {  
            "_index":"my-index",
            "_type":"_doc",
            "_id":"2",
            "_score":2.1576157,
            "_source":{  
               "query":{  
                  "match":{  
                     "title":"the enojen tree in a kerojen"
                  }
               }
            },
            "fields":{  
               "_percolator_document_slot":[  
                  0
               ]
            },
            "highlight":{  
               "title":[  
                  "<em>A</em> new bonsai <em>tree</em> <em>in</em> <em>the</em> office and jungle. <em>The</em> <em>enojen</em> <em>tree</em> <em>in</em> <em>a</em> <em>kerojen</em>."
               ]
            }
         },
         {  
            "_index":"my-index",
            "_type":"_doc",
            "_id":"1",
            "_score":2.1576157,
            "_source":{  
               "query":{  
                  "match":{  
                     "title":"the bonsai tree in a jungle"
                  }
               }
            },
            "fields":{  
               "_percolator_document_slot":[  
                  0
               ]
            },
            "highlight":{  
               "title":[  
                  "<em>A</em> new <em>bonsai</em> <em>tree</em> <em>in</em> <em>the</em> office and <em>jungle</em>. <em>The</em> enojen <em>tree</em> <em>in</em> <em>a</em> kerojen."
               ]
            }
         }
      ]
   }
}

正如您所看到的,我们正在逐字逐句地分割所有突出显示的匹配,但我们希望得到如下内容:<em>The enojen tree in a kerojen</em>;它有一个相关的issue

我们正在搜索它,我们发现了这个question,但它与Sorl有关。

它说为此目的有两个可能的参数(来自Lucene):usePhraseHighlightermergeContiguous

那么,我们如何才能获得一个完整的短语突出显示结果,而是单独突出显示每个单词的短语查询?

谢谢。
