How can I use the .search() method more efficiently in Javascript?

I am currently using the Javascript Search() method to search for a match in a string. I want to find the closest match, for example, if the string is 'apple iphone', and a person searches 'iphone 6' I want there to be a match, but for some reason, the .search method doesn't work this way.

Is there a more efficient way to use this or another method that can be more useful?

const test = "apple iphone"
// this doesn't return -1 indicating there was a match
console.log(test.search('iphone'))

// this returns -1 indicating there wasn't any match at all despite there 
// being the word "iphone" in there 
console.log(test.search('iphone 5'))

If you mean searching something 'apple' OR 'iphone', use it as condition.

'iphone'.search(/apple|iphone/);    //this doesn't return -1
'iphone 5'.search(/apple|iphone/);   //this doesn't return -1

Match two strings with the same word in JavaScript

From the answer above , I think the flowing code is what you are looking for : 

<script>
 var m = "apple iphone".split(' ');
   var n = "iphone 6".split(' ');
      var isOk=0;

    for (var i=0;i<m.length;i++)
 {
    for (var j=0;j<n.length;j++)

 {
    var reg = new RegExp("^"+m[i]+"$", "gi");

  if (n[j].match(reg) )
   {isOk=1;break;}
          }
        }

     if (isOk==1)
       alert("match");

 </script>

You can use below sample code.

const test = 'apple iphone'

const term = 'iphone 5'

// Split by whitespace
const terms = term.split(/\s/)

// Test all sub term
const result = terms.reduce(function(previousValue, currentValue) {
  if (test.search(currentValue) > -1) previousValue.push(currentValue)
  return previousValue
}, [])

console.log(result.length > 0)
