fast vector highlighter not working properly with the percolator

[brwe]

Results when using fast vector highlighter with the percolator are wrong. The test below reproduces this. The reason is a bug in MemoryIndex, see https://issues.apache.org/jira/browse/LUCENE-5444

Will be resolved with lucene 4.7

DELETE phrasetest


PUT phrasetest
{
   "mappings": {
      "doc": {
         "properties": {
            "body": {
               "properties": {
                  "text": {
                     "type": "string",
                     "term_vector": "with_positions_offsets"
                  }
               }
            }
         }
      }
   }
}

POST phrasetest/_refresh

POST phrasetest/.percolator/Q
{
   "query": {
      "match": {
         "text": {
            "query": "foo bar"
         }
      }
   }
}


POST phrasetest/doc/_percolate
{
   "doc": {
      "body": [
         {
            "text": "la la"
         },
         {
            "text": "foo bar foo bar foo"
         }
      ]
   },
   "size": 1,
   "highlight": {

            "number_of_fragments": 20
         }
      }
   }
}

yields:
