When searching using LIKE search for basic searches is fine, when you need greater control Full-Text searches is far greater.
Laravel does not support Full-Text searches due to it being too MySQL specific. However, it can still be used by using RAW queries
In whereRaw specify MATCH followed by the columns to search then specify AGAINST ? place holder which will be replaced when executes with the values from an array.
Product::whereRaw('MATCH (title, content) AGAINST (?)' , array($search))->get();
In order for this to work, you will need to add Full-Text index against your table columns in MySQL.
DB::statement('ALTER TABLE products ADD FULLTEXT fulltext_index (title, content)');
