I need to write my own function inside the search template like **toJson**

```auto
.............
"functions": [
				{
					"filter": { 
						"terms": { 
							"empId": {{#my_own_function}}PARAM_VALUE{{/my_own_function}} 
						}
					}, 
					"weight": 20
				}
			],
			"score_mode": "multiply"
.........................................

```
