Indexing in JPA to ensure a good performance when searching for yearly data?

Hi, I am trying to figure out if my indexing makes sense: 
package com.example.demo.model;

import jakarta.persistence.*;
import jakarta.validation.constraints.DecimalMin;
import jakarta.validation.constraints.NotBlank;
import jakarta.validation.constraints.NotNull;
import java.math.BigDecimal;
import java.time.LocalDateTime;

@Entity 
@Table(name = "payment", indexes = {
        @Index(name = "idx_payment_company_payment_service_date", columnList = "company_id, payment_service_id, YEAR(date)") 
})
public class Payment {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    @Column(name = "payment_id", updatable = false, nullable = false)
    private Long paymentId;

    @DecimalMin(value = "0.01", message = "Amount must be greater than 0")
    @Column(name = "amount", nullable = false, precision = 10, scale = 2)
    private BigDecimal amount;

    @NotNull(message = "Date of payment must be specified")
    @Column(name = "date", nullable = false)
    private LocalDateTime date;

    @NotBlank(message = "Payment method must be specified")
    @Column(name = "payment_method", nullable = false)
    private String paymentMethod;

    @NotNull
    @ManyToOne(fetch = FetchType.LAZY) 
    @JoinColumn(name = "company_id", nullable = false)
    private Company company;

    @NotNull
    @ManyToOne(fetch = FetchType.LAZY) 
    @JoinColumn(name = "payer_id", nullable = false)
    private Payer payer;

    @NotNull
    @ManyToOne(fetch = FetchType.LAZY) 
    @JoinColumn(name = "payment_service_id", nullable = false)
    private PaymentService paymentService;

    // Getters and Setters...
}
package com.example.demo.model;

import jakarta.persistence.*;
import jakarta.validation.constraints.DecimalMin;
import jakarta.validation.constraints.NotBlank;
import jakarta.validation.constraints.NotNull;
import java.math.BigDecimal;
import java.time.LocalDateTime;

@Entity 
@Table(name = "payment", indexes = {
        @Index(name = "idx_payment_company_payment_service_date", columnList = "company_id, payment_service_id, YEAR(date)") 
})
public class Payment {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    @Column(name = "payment_id", updatable = false, nullable = false)
    private Long paymentId;

    @DecimalMin(value = "0.01", message = "Amount must be greater than 0")
    @Column(name = "amount", nullable = false, precision = 10, scale = 2)
    private BigDecimal amount;

    @NotNull(message = "Date of payment must be specified")
    @Column(name = "date", nullable = false)
    private LocalDateTime date;

    @NotBlank(message = "Payment method must be specified")
    @Column(name = "payment_method", nullable = false)
    private String paymentMethod;

    @NotNull
    @ManyToOne(fetch = FetchType.LAZY) 
    @JoinColumn(name = "company_id", nullable = false)
    private Company company;

    @NotNull
    @ManyToOne(fetch = FetchType.LAZY) 
    @JoinColumn(name = "payer_id", nullable = false)
    private Payer payer;

    @NotNull
    @ManyToOne(fetch = FetchType.LAZY) 
    @JoinColumn(name = "payment_service_id", nullable = false)
    private PaymentService paymentService;

    // Getters and Setters...
}
I need to be able to quickly lookup yearly payments that a given company have received for a given year.
