Is it possible to check if a string contains the word in a nested array? I am accessing the fields through params.\_source and I have created a painless script as below, but it's throwing me errors at contains(). How to check f string contains a word with params.\_source using contains()?

```auto
"script_fields": {
	"recency": {
		"script": {
			"lang": "painless",
			"inline": """
				def myString = "";
				def isCurrent = 0;
				def list = new ArrayList();
				for(int i=0; i<params._source.candidate.work_exp.size(); i++){
					myString = params._source.candidate.work_exp[i].description;
					if(myString.toString().contains(params['search_keywords'])){
						isCurrent=0;
						list.add(myString);
					} 
				}
					return list;
					""",
			"params": {
				"search_keywords": keywords
			}

		}
	}
}

```
