Steps to reproduce the issue

1. Use the query

   POST /drugv1/terms/_search
   {
   "from": 0,
   "size": 200,
   "_source": {
       "includes": [
           "aliases",
           "definition",
           "term_id",
           "name",
           "first_letter",
           "type",
           "term_name_type",
           "pretty_url_name",
           "preferred_name"
       ]
   },
   "sort": [ { "name": {} } ],
   "query": {
       "bool": {
           "should": [
               {
                   "bool": {
                       "must": [
                           { "match": { "name._contain": { "query": "paclitaxel" } } },
                           { "term": { "type": { "value": "DrugTerm" } } }
                       ]
                   }
               },
               {
                   "nested": {
                       "query": { "match": { "alias.name._contain": { "query": "paclitaxel" } } },
                       "path": "aliases"
                   }
               }
           ]
       }
   }
   }

What's the expected result?

• The results should include the term carboplatin-Taxol regimen which has carboplatin-paclitaxel regimen as an alias.

What's the actual result?

• The term is not included in the results.

Oh for crying out loud.... It's a typo. in the nested portion.

{
    "nested": {
        "query": { "match": { "alias.name._contain": { "query": "paclitaxel" } } },
        "path": "aliases"
    }
}

The match should be for aliases not alias.
