Hello i want to add more than 1 tag in my if else statement below [if (hit.transform.gameObject.tag.Equals("object"))] so how can i use AND operator to add more tags thanks here is my code

using System.Collections;
using System.Collections.Generic;

using UnityEngine.UI;

public class ToolTip : MonoBehaviour {

public RectTransform tooltip;
public Text tooltiptext;
public Vector2 offset;
public LayerMask lm;

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {
    RaycastHit hit = new RaycastHit();
    Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
    if (Physics.Raycast(ray, out hit, lm))
    {
        if (hit.transform.gameObject.tag.Equals("object"))
        {
        tooltip.gameObject.SetActive(true);
        tooltiptext.text = hit.transform.name;
        tooltip.position = new Vector3(Input.mousePosition.x + offset.x,
            Input.mousePosition.y + offset.y);

    }

    }

    else
    {
        tooltip.gameObject.SetActive(false);
