Hello All,

Match Query:

    {
   "query":{  
      "bool":{  
         "should":[  
            {  
               "match":{  
                  "nAME":{  
                     "analyzer":"my_fuzzy_analyzer",
                     "fuzziness":"AUTO:1,4",
                     "fuzzy_transpositions":true,
                     "max_expansions":2147483647,
                     "minimum_should_match":-1,
                     "operator":"and",
                     "prefix_length":3,
                     "query":"SHENZHEN LONGTANUO LOGISTICS       C                                  "
                  }
               }
            }
         ]
      }
   }
}

Expected Results:

SHENZHEN LONGTANUO LOGISTICS       C                                  
SHENZHEN LUCKY LOGISTICS LTD.

Thank means that all terms present in the query have to match. You need to replace it with or. Please, see documentation for more information on the topic.
