How can I do a one-to-one search in the title field?

[Busra_Duygu (Büşra Duygu)]

When I tried with .keyword it failed again, but when I tried with .raw it succeeded..

GET my_index_name/_search
{
  "query": {
   "wildcard": {
     "Title.raw": {
       "value": "*BREMAX SA*",
       "case_insensitive": true
     }
   }
  }
}

@can.ozdemir thank you so much for helping
