Đối với chức năng tìm kiếm, tôi đang sử dụng chế độ xem có các bản ghi từ tất cả các bảng mà tôi cần tìm kiếm. Lượt xem có gần 20 triệu hồ sơ. Tìm kiếm chống lại quan điểm này đang mất quá nhiều thời gian.
Tôi nên tìm ở đâu để cải thiện hiệu suất của quan điểm này?
Định nghĩa sơ bộ cho quan điểm dưới đây. Nó bao gồm mười ba bảng và khoảng ba mươi lĩnh vực.
