Java String.matches giving wrong result

I am using String.matches to search a pattern which is present in my input string, but I am getting wrong result. Below is my code.

public class Main {

    public static void main(String[] args) {
        String text =
                "WHERE  ( d.day_key = fact.day_key  \n" +
                    "AND d.full_date BETWEEN  '2013-10-01' AND '2013-12-05' \n" +
                    "AND advac.account_key = fact.advertiser_account_key  \n" +
                    "AND cam.campaign_key = fact.campaign_key  \n" +
                    "AND advac.account_name = 'abc.com') \n";

System.out.println(text.matches("(.*)full_date(.*)"));

    }

}

The above code prints false. Is there anything wrong with my regex? Please advice.

You need to enable dotall mode if you want . to also match new line characters. This can for example be done like this: 

text.matches("(?s)(.*)full_date(.*)");

You can read more in the JavaDocs.

The problem is that your input contains newlines, so you need to pass the right flag in the regex otherwise the dot metacharacter won't match:

text.matches("(?s)(.*)full_date(.*)")
