Laravel Eloquent orWhere 没有按预期工作

Question

这个 Eloquent 查询似乎没有按预期工作。

如果我传入一个术语然后是类别然后是制造商，它会按预期工作，但只输入制造商会产生零结果，制造商也是如此。

这是我的网址... /products?term=12&category=2&manufacturer=3

这里是 toSql() 的转储 "select * from products where id = ? or model like ? or category_id = ? or manufacturer_id = ?"

        $term = $request->input('term');
        $category = $request->input('category');
        $manufacturer = $request->input('manufacturer');

        $products = Product::orWhere('id', $term)
               ->orWhere('model', 'like', "%{$term}%")
               ->orWhere('category_id', $category)
               ->orWhere('manufacturer_id', $manufacturer)
               ->get();

难倒，任何帮助将不胜感激。

$term = $request->input('term');
$category = $request->input('category');
$manufacturer = $request->input('manufacturer');

$products = Product::where(function ($query) use ($request,$term,$category,$manufacturer) {
if($request->filled('term'))
   $query->orWhere('model', 'like', "%{$term}%")->orWhere('id', $term);
if($request->filled('category'))
   $query->orWhere('category_id', $category);
if($request->filled('manufacturer'))
   $query->orWhere('manufacturer_id', $manufacturer);

})->latest()
->paginate(5);
