How to improve the search on the site?

Question

JavaScript

Friends, tell me. Wrote a search. For example, we have an article in the "Lorem ipsum 2" database. If I enter
the letters from the title in order, then the article is returned, and if, for example, "Lorem 2", then it is not returned. How to make it come back?

$('.search-field').on('keyup', function(){
    var words = $(this).val().trim();

    $.ajax({

      url: "/search",
      type: "post",
      data: {words: words},
      headers: {
            	'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
            },

      success: function(results) {
        $.each(results, function(key,result){
          $('.search-results > div > a').text(result.title)
        })
      }

    })	
    
  })

public function search() 
  {
    $words = Request::get('words');
    $results = Articles::where('title', 'LIKE', '%' . $words . '%') -> get();
    return $results;
  }

Answer 1

Use a dedicated full text search solution: Elastic, Sphinx

Answer 2

Break the search word by spaces and look for the occurrence of each element using AND, OR, and the %...%.
AND or OR it is up to you to decide how inaccurate it will show the results
. If it is AND, then it will find articles with lorem and 2 in the text. (Both are present)
If there is an OR, it will find everything with lorem and everything with 2 (That is, only one or the other)

public function search() 
  {
   $items = explode(" ",Request::get('words'));

    $Articles = new Articles();

    foreach ($items as $item){
        $Articles->where('title', 'LIKE', '%' . $words . '%')
        // $Articles->orWhere('title', 'LIKE', '%' . $words . '%') тут как хотите
    }

    $results = $Articles -> get();
    return $results;
  }
