如何使用从widget文本框中输入的单词来搜索数据框，然后使用python、ipywidgets显示搜索结果？

import pandas as pd
import ipywidgets as widgets
from IPython.display import display

data = {'Name': ['John', 'Alice', 'Bob', 'Emily'],
        'Age': [25, 30, 35, 40],
        'City': ['New York', 'Paris', 'London', 'Tokyo']}
df = pd.DataFrame(data)

search_box = widgets.Text(placeholder='输入关键词', description='搜索：')

output = widgets.Output()

def search_data(sender):
    output.clear_output()
    search_term = search_box.value.lower()
    filtered_df = df[df['Name'].str.lower().str.contains(search_term)]
    with output:
        display(filtered_df)

# 将搜索函数与文本框的on_submit事件关联
search_box.on_submit(search_data)

display(search_box)
display(output)
