Phrase Highlighter

[keremcan]

Hi there, I'm trying to highlight a phrase not a word. When trying this, ES searching everyword in my query, and tags with <em>. I want to tag them as phrase not every single word. Here is an example:

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": {}
      }
    }
}
'

output:

            "_score":2.1576157,
            "_source":{

                  }
               }
            },
            "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."
               ]
            }
         }
      ]
   }
}

I want highlighted words to combine like <em>The enojen tree in a kerojen</em>
Any suggestion would be appreciated!
