Implementing Full text search in Laravel 4.2 for Autocomplete search

Posted 8 years ago By Ajay Gupta 17832

Here i will tell you the best searching pattern using full text search in Laravel. If you have a question that is it possible full text search in Laravel then my answer is yes.

Make sure full text search do not work with every database server that's the reason Laravel 4 removed this feature but it can still easily executed.

A full text index in MySQL is also known as an index of type FULLTEXT. Full-text is only compatible with MyISAM tables.

Full text can be created only for TEXT, CHAR and VARCHAR fields.

Add route

Route::get('search', array('as' => 'search', 'uses' => 'SearchController@autosuggest'));

Route::get('search', array('as' => 'search', 'uses' => 'SearchController@autosuggest'));

Create Controller functions

Now create a autosuggest function in your controller for generating result using full text search.

    public function autosuggest()
    {
        $keyword = Input::get('query');
        $keyword = preg_replace('/[^A-Za-z0-9\ ]/', '', $keyword) ;
        $suggestions = SearchIndex::select('searchable_type', 'searchable_id','priority', 'item_title', 'item_description',
            DB::raw('(match (keywords) against (\'' . $keyword . '\')) as score'),
            DB::raw('(match (item_title) against (\'' . $keyword . '\')) as score2')
        )
            ->whereRaw('match (keywords) against (\'' . $keyword . '\')')
            ->orWhereRaw('match (item_title) against (\'' . $keyword . '\')')
        
            ->orderBy(DB::raw('score+score2*2'), 'desc')
            ->take(20)
            ->get();
        return return View::make('home.index', compact('suggestions'));
    }

    public function autosuggest()    {        $keyword = Input::get('query');        $keyword = preg_replace('/[^A-Za-z0-9\ ]/', '', $keyword) ;        $suggestions = SearchIndex::select('searchable_type', 'searchable_id','priority', 'item_title', 'item_description',            DB::raw('(match (keywords) against (\'' . $keyword . '\')) as score'),            DB::raw('(match (item_title) against (\'' . $keyword . '\')) as score2')        )            ->whereRaw('match (keywords) against (\'' . $keyword . '\')')            ->orWhereRaw('match (item_title) against (\'' . $keyword . '\')')                    ->orderBy(DB::raw('score+score2*2'), 'desc')            ->take(20)            ->get();        return return View::make('home.index', compact('suggestions'));    }

Now Add this form in your view file

{{ Form::open(array('route' => 'search','method' => 'get', 'class'=>'form-inline')) }}
    <div class="input-group input-group-lg">
        <input style="width: 99%" autocomplete="off" type="text" class="form-control input-lg" id="keyword" name="keyword" placeholder="Search tutorials articles..">
        <span class="input-group-btn" style="width: 1%">
        <button style="margin-top: -6px" class="btn btn-primary btn-lg" id="submit" type="submit"><i class="fa fa-search">i>button>
          span>
    div>
{{ Form::close() }}

{{ Form::open(array('route' => 'search','method' => 'get', 'class'=>'form-inline')) }}            
                      	    
{{ Form::close() }}
