A RegEx and filter to remove duplicates;

var string = "I put putty on the computer. putty, PUT do I"

var uniques = {};
var result = (string.match(/\b\w*put\w*\b/ig) || []).filter(function(item) {
   item = item.toLowerCase();
   return uniques[item] ? false : (uniques[item] = true);
});

document.write( result.join(", ") );

// put, putty, computer

One way to do what you're asking is to split the input string into tokens, then check each one to see if it contains the desired substring. To eliminate duplicates, store the words in an object and only put a word into the result list if you're seeing it for the first time.

function findUniqueWordsWithSubstring(text, sub) {
    var words = text.split(' '),
        resultHash = {},
        result = [];
    for (var i = 0; i < words.length; ++i) {
        var word = words[i];
        if (word.indexOf(sub) == -1) {
            continue;
        }
        if (resultHash[word] === undefined) {
            resultHash[word] = true;
            result.push(word);
        }
    }
    return result;
}

var input = 'put some putty on the computer output',
    words = findUniqueWordsWithSubstring(input, 'put');
alert(words.join(', '));
