I'm using Elasticsearch 1.4.1 (lucene_version 4.10.2) and have a search 
that works well with most search strings, but fails spectacularly on 
others. Experimenting, it appears to fail when at least one word in the 
query doesn't match in any documents (like the second word in the made up 
search phrase below). It fails with the error:

{
   "error": "SearchPhaseExecutionException[Failed to execute phase 
[query_fetch], all shards failed; shardFailures 
{[w3zfoix_Qi-xwpVGbCbQWw][ia_test][0]: 
ElasticsearchIllegalArgumentException[the field [content] should be indexed 
with positions and offsets in the postings list to be used with postings 
highlighter]}]",
   "status": 400
}

The simplest search which gives this error is shown below:

POST /myindex/_search
{
    "from" : 0,
    "size" : 25,
    "query": {
        "filtered" : {
            "query" : {
                "multi_match" : {
                    "type" : "most_fields",
                    "fields": ["title", "content", "content.english"],
                    "query": "Box Fexye"
                }
            }
        }
    },
    "highlight" : {
        "fields" : {
            "content" : {
                "type" : "postings"
            }
        }
    }
}

The index definition for these fields looks like:

{
    "properties" : {
        "title" : {
            "type" : "string",
            "fields": {
                "shingles": {
                    "type":     "string",
                    "analyzer": "my_shingle_analyzer"
                }
            }
        },
        "content" : {
            "type" : "string",
            "analyzer" : "standard",
            "fields": {
                "english": {
                    "type":     "string",
                    "analyzer": "my_english"
                },
                "shingles": {
                    "type":     "string",
                    "analyzer": "my_shingle_analyzer"
                }
            },
            "index_options" : "offsets",
            "term_vector" : "with_positions_offsets"
        }
    }
}

Is user error involved here, or is there something ES can't handle?

Thanks,
Peter
