@polyfractal -

Resolved. Thanks for your explanation. I changed value as lowercase in query and then query brings back results as expected.

Checked mapping -

"name" : {
          "type" : "text",
          "index_options" : "offsets"
        },

Also found these settings from Mapping

"settings" : {
      "index" : {
        "number_of_shards" : "5",
        "provided_name" : "XXXXXXX",
        "gc_deletes" : "24h",
        "creation_date" : "1578423989207",
        "analysis" : {
          "analyzer" : {
            "keyword_lowercase" : {
              "filter" : [
                "lowercase"
              ],
              "type" : "custom",
              "tokenizer" : "keyword"
            }
          }
        },
