如何进行多过滤搜索？

Question

I'm building an ecommerce site with Vanilla JS, Node and MongoDB. My search bar currently can only return searches based upon the name of the product as follows:

productRouter.get('/', expressAsyncHandler(async (req, res) => {
    const searchKeyword = req.query.searchKeyword
    ? {
        name: {
            $regex: req.query.searchKeyword,
            $options: 'i'
            }
        }
    : {};
    const products = await Product.find({...searchKeyword});
    res.send(products);
    })
);

I've tried adding category and brand inside of the ? {} like so to no avail:

? {
        name: {
            $regex: req.query.searchKeyword,
            $options: 'i'
            }, 
        category: {
            $regex: req.query.searchKeyword,
            $options: 'i'
            }, 
        brand: {
            $regex: req.query.searchKeyword,
            $options: 'i'
            }
  }

Thanks!

You could use the search text feature.

It would be something like this:

// Creating compound index on db
db.product.createIndex({ name: 'text', category: 'text', brand: 'text' })

// Executing query
db.product.find({ $text: { $search: "something" } })

If you're using Mongoose, here is demonstrating how to create an index.
