I'm trying to search a particular word on the input field and perform if/else condition accordantly. for an example input field can be "iPhone 6" or "Apple iPhone 5" or " Samsung A7" o "S9 Samsung" etc. Please help me find word "iPhone" or "Samsung" from the input field apply if/ else condition. 

<input type="text" id="ModelNo" />
<script>
var Model_Validation = document.getElementById("ModelNo").value;
var Model_1 = "iPhone";
var Model_2 = "Samsung";

function test() {
    if (Model_Validation == Model_1) {

    } else if (Model_Validation == Model_2) {

    } else {}
}
</script>

I doubt which logic to use in if condition as well. hope my question is clear.

You can use the includes method on your input's text.

let input = document.getElementById("ModelNo").value; 

if(input.includes(Model_1)){/* do something*/}
else (input.includes(Model_2)){/* do something else*/}

Or you can use a regular expression but includes should be more efficient and simple for what you want to do.

This could be achieved with JQuery:

<input id="search" type="input" value="type here"/>
<div id="result"></div>

$(document).ready(function(){
    $("#search").on('input',function(){
    var userinput = $(this)[0].value;
    if(userinput == 'samsung'){
        $("#result").html('user inserted "samsung"');
    }
    else{
        $("#result").html(userinput);
    }
  })
});
