jQuery filters + bootstrap with multiple keywords

Question

I am looking to modify the bootstrap filter to search for multiple keywords.

In the example below, you can only search for one continuous keyword, such as "john" or "doe. Whereas I am looking to type in "oh do" (or "do oh") and it should return the first row of "john doe john@example.com".

I have been searching for some other examples such as: this and this. but I can't quite get that to work, and the first example is quite slow compare to the example posted above...

I manage to figure if i can somehow do this with toggle:

$(this).toggle($(this).text().toLowerCase().indexOf(value1) > -1 && $(this).text().toLowerCase().indexOf(value2) > -1)

then it would return the result that I am looking for, it would be easy if it is always two keywords, then this would work perfectly fine. But in a real world scenario, in a larger table, we can never predict how many keywords an user will put in, it could be 4 or 5, or could be 1... and being new in coding and only have been working in python/django doesn't help to understand and modify this jquery code to achieve the result...

is there anyone out there that can give it a shot?

$(document).ready(function(){
  $("#myInput").on("keyup", function() {
    var value = $(this).val().toLowerCase();
    $("#myTable tr").filter(function() {
      $(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
    });
  });
});

Not short code but you can try this

function checkInput(element, value) {
  value = value.split(' ');
  for (var i = 0; i < value.length; i++) {
    if (value[i] && element.text().toLowerCase().indexOf(value[i]) == -1) return false;
  }
  return true;
}

$(document).ready(function() {
  $("#myInput").on("input", function() {
    var value = $(this).val().toLowerCase();
    $("#myTable tr").filter(function() {
      $(this).toggle(checkInput($(this), value))
    });
  });
});

using es6 every() all browser and IE9+

$(this).toggle(
    value.split(' ').every(val => $(this).text().toLowerCase().indexOf(val) > -1)
)
