it helps some times One method would be to use a MySQL REGEXP call in a Predicate Expression.
Where $select is an instance of Zend\Db\Sql\Select and $searchFor is your search term:
code :
$select->where(array(
    new Predicate\PredicateSet(
        array(
            new Zend\Db\Sql\Predicate\Like('tag', '%' . $searchFor . '%'),
            new Zend\Db\Sql\Predicate\Like('title', '%' . $searchFor . '%'),
        ),
        Zend\Db\Sql\Predicate\PredicateSet::COMBINED_BY_OR
    ),
));
$select->where(array(
    new Predicate\PredicateSet(
        array(
            new Zend\Db\Sql\Predicate\Expression("tag REGEXP '([[:<:]]" . $searchFor ."[[:>:]])'"),
            new Zend\Db\Sql\Predicate\Expression("title REGEXP '([[:<:]]" . $searchFor ."[[:>:]])'"),
        ),
        Zend\Db\Sql\Predicate\PredicateSet::COMBINED_BY_OR
    ),
));

I think the issue was by ths following , I'm assuming you'll allow any non-whitespace characters before or after foo.
Then you can use
code :
'^[^[:space:]]*'.$word.'[^[:space:]]*$'
^\S*foo\S*$

will be helpful for those in need You should not break the loop there since it is only considered not found once you went through all the sentences in the array. Something like this:
code :
public static void main(String[] args) {
    String[] str={"I am Alive.","Are you dead?","Let's see if it works."};
    String search;

    Scanner s=new Scanner(System.in);
    System.out.println("Enter word");
    search=s.nextLine();

    boolean found = false;
    for(int i=0;i<str.length;i++){
        if(str[i].contains(search)){
            System.out.println(str[i]);
            found = true;
        }
    }

    if (!found) {
        System.out.println("Not found");
    }
}

fixed the issue. Will look into that further I want to recommend wordboundary syntax like this: REGEXP '[[:<:]]demo[[:>:]]'
http://sqlfiddle.com/#!9/d63e05/1
code :
SELECT * FROM address WHERE address REGEXP '[[:<:]]demo[[:>:]]' AND 'demo' REGEXP '[0-9]'

wish helps you I'm using the following regex to search for 3 different string formats, concurrently. Additionally, I'm using re.IGNORECASE to match upper and lower case strings. However, when I perform a search (e.g. 'locality'), I'm able to get string matches for 'localit', 'locali', 'local' and so on and so forth. I want to match the exact word (eg. 'locality'). , There is no such flag in re, so either:
