如果有搜索词“iphone7s”，如何先搜索“iphone”，然后搜索“7s”，并在一个变量中获得所有结果

如果有搜索词“iphone7s”，那么如何先搜索“iphone”呢 “7s”并在一个变量中获得所有结果

使用这个自动完成，这是我在Laravel5.4中使用的代码

$('#search').on('input', function(){
    var search = $('#search').val(); //search input var

    if(search.length == 0){
        //do something if value of search box is empty
    } else {
        $('#search').autocomplete({
            source: function(request, response){
                $.ajax({
                    url: 'search', //route
                    data: { search:search },
                    dataType: 'json',
                    type: 'post',
                    success: function(data){
                        //here is your data
                    },
                    error: function(){
                        alert('Could not load the data');
                    }
                });
            }
        });
    }
});

如果我理解正确，您希望为每个单词应用

或where（）

与

foreach

配对：

$words = explode(' ', $search);

$result = Product::query();

foreach ($words as $word) {
    $result = $result->orWhere('originalname', 'like', '%'.$word.'%')
                     ->orWhere('name', 'like', '%'.$word.'%');
}

$result = $result->orderby("products.table_id")->take(5)->get();

我的jquery工作，我不知道php如何用N个单词选择数据自动完成
不包括在jquery核心中如果你能帮我写这段代码，如何从mysql中选择行，就像所有的单词一样，如果我有“Iphone 7s blue”并且我搜索“Iphone blue”，那么就只得到只有这个单词的行如果你理解我，因为我不懂英文SQL sintax，所以请从产品中选择*，其中名称%iphone%和名称%blue%使用两个或where（）
闭包。一个是名字，另一个是原名。内部闭包使用foreach和where（）将所有单词添加到搜索中。我在mysql中有三星galaxy s7、三星galaxy s6、三星galaxy s8，如果我搜索三星s7，此代码将告诉我所有三星如何修改仅包含此单词的行，从名称为%Samsung%和名称为%s7%的产品中选择*
