Combine Query string Query with rank_feature query Elasticsearch

Question

i am using query string query for full-text search across multiple text fields. The fields contain product short descriptions in different languages. Another relevant field is the "article number" field. i am interested in the article number of products that is displayed along with the matching document in the resulting response. In other words, i am using the full-text query to search for products but more importantly to search for the associated "article number".

is it possible to search for the product using the full-text query and at the same time searching for the article number with the highest frequency associated to the product.

How it is possible to highlight article numbers with higher frequency when searching for documents? Can i use the rank feature query for this purpose?

 {
   "query" : {
        "bool":  {
             "schould": {
              "query_string" : {
                    "query": "desktop equipments"
                     "fields" : ["content.en", "content.de", "content.fr", "content.fr"]
                        }
                     }
                   },
               {
                 "rank_feature" : {
                       "field" : "article_number",
                        "boost": 0.4
            }}}}
