Can not able to get search results Need some help with query

[vishwas_jadav]

I have already created an index and I daily add some records and use in a site for searching.
Now, I have created another index and in that I used Data types as I have used in my previous index.
but I am not getting any results.

Here is the mapping for my index:

{
	"euipo" : {
		"mappings" : {
			"text_type" : {
				"properties" : {
					"applicant_date" : {
						"type" : "integer"
					},
					"applicant_name" : {
						"type" : "completion",
						"analyzer" : "simple",
						"preserve_separators" : true,
						"preserve_position_increments" : true,
						"max_input_length" : 50
					},
					"application_date" : {
						"type" : "long"
					},
					"application_number" : {
						"type" : "completion",
						"analyzer" : "simple",
						"preserve_separators" : true,
						"preserve_position_increments" : true,
						"max_input_length" : 50
					},
					"class_number" : {
						"type" : "completion",
						"analyzer" : "simple",
						"preserve_separators" : true,
						"preserve_position_increments" : true,
						"max_input_length" : 50
					},
					"did" : {
						"type" : "long"
					},
					"id" : {
						"type" : "text"
					},
					"mark_text" : {
						"type" : "completion",
						"analyzer" : "simple",
						"preserve_separators" : true,
						"preserve_position_increments" : true,
						"max_input_length" : 50
					}
				}
			}
		}
	}
}

there is the screen shot of the query I used :
