如何在firebase实时数据库android中搜索多个子

Question

我正在处理一个android项目。我的情况是我已经可以在Firebase数据库中搜索search_name值，但是我想搜索数据库中的所有相对值

  

例如：已经搜索了“ search_name”，但现在我想   跟随孩子的search_category，search_description，search_fabric

这是我的数据库结构

这是我的代码：

DatabaseReference reference = FirebaseDatabase.getInstance().getReference().child("Products");

        FirebaseRecyclerOptions<Products> options = new FirebaseRecyclerOptions.Builder<Products>()
                .setQuery(reference.orderByChild("search_name").startAt(SeachInputText).endAt(SeachInputText+"\uf8ff"), Products.class)
                .build();


        FirebaseRecyclerAdapter<Products, ProductViewHolder> adapter =
        new FirebaseRecyclerAdapter<Products, ProductViewHolder>(options) {
            @Override
            protected void onBindViewHolder(@NonNull ProductViewHolder holder, int position, @NonNull final Products model)
            {
                holder.jProduct_name.setText(model.getName());
                holder.jProduct_price.setText("Price = ₹" + model.getPrice());
                holder.jAvail_size.setText(model.getAvailable_size());
                Picasso.get().load(model.getImage()).into(holder.jProduct_image);
                holder.itemView.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view)
                    {
                        Intent intent=new Intent(SearchProductsActivity.this,ProductDetailsActivity.class);
                        intent.putExtra("pid",model.getPid());
                        startActivity(intent);
                        finish();
                    }
                });}

            @NonNull
            @Override
            public ProductViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int i)
            {
                View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.product_items_layout, parent, false);
                ProductViewHolder holder = new ProductViewHolder(view);
                return holder;
            }
        };

        jList.setAdapter(adapter);
        adapter.startListening();
    }
