ElasticSearch: TooManyClauses exception when adding selection

My query_string is giving me a TooManyClauses exception. However, in my case, I don't think the exception is being thrown due to the usual reason . Instead, it seems to have something to do with highlighting, because when I remove the highlight from the request, it works. This is my initial request:

{
    "query" : {
        "query_string" : {
            "query" : "aluminium potassium +DOS_UUID:*",
            "default_field" : "fileTextContent.fileTextContentAnalyzed"
        }
    },
    "fields" : [ "attachmentType", "DOS_UUID", "ATT_UUID", "DOCUMENT_REFERENCE", "filename", "isCSR", "mime" ],
    "highlight" : {
        "fields" : {
            "fileTextContent.fileTextContentAnalyzed" : { }
        }
    }
}   

      

        
        
        
      

    

and this gives me the TooManyClauses error:

{
   "error": "SearchPhaseExecutionException[Failed to execute phase [query_fetch], all shards failed; shardFailures {[02Z45jhrTCu7bSYy-XSW_g][markosindex][0]: FetchPhaseExecutionException[[markosindex][0]: query[filtered(fileTextContent.fileTextContentAnalyzed:aluminium fileTextContent.fileTextContentAnalyzed:potassium +DOS_UUID:*)->cache(_type:markostype)],from[0],size[10]: Fetch Failed [Failed to highlight field [fileTextContent.fileTextContentAnalyzed]]]; nested: TooManyClauses[maxClauseCount is set to 1024]; }]",
   "status": 500
}

      

        
        
        
      

    

This is a non-highlighting query that works:

{
    "query" : {
        "query_string" : {
            "query" : "aluminium potassium +DOS_UUID:*",
                    "default_field" : "fileTextContent.fileTextContentAnalyzed"
        }
    },
    "fields" : [ "attachmentType", "DOS_UUID", "ATT_UUID", "DOCUMENT_REFERENCE", "filename", "isCSR", "mime" ]
}

      

        
        
        
      

    

UPDATE 1:

This is the stack from the ElasticSearch log file:

Note. I am using ElasticSearch 1.2.1.

UPDATE 2:

This is my mapping:

{
   "markosindex": {
      "mappings": {
         "markostype": {
            "_id": {

               },

               "isCSR": {
                  "type": "boolean"
               },
               "mime": {
                  "type": "string",
                  "index": "not_analyzed"
               }
            }
         }
      }
   }
}

      

        
        
        
      

    

Any idea? Thank!
