获取字符串和数组中包含的短语列表

const str = "This is a sample string. Sample phrase is included in this string.";
const phrase = "sample phrase";
const regex = new RegExp(phrase, "gi");
const matches = str.match(regex);
console.log(matches); // ["Sample phrase"]

import re

str = "This is a sample string. Sample phrase is included in this string."
phrase = "sample phrase"
matches = re.findall(phrase, str, re.IGNORECASE)
print(matches) # ['Sample phrase']

const arr = ["This is a sample string.", "Sample phrase is included in this string.", "Another sample phrase."];
const phrase = "sample phrase";
const matches = arr.filter(item => item.toLowerCase().includes(phrase.toLowerCase()));
console.log(matches); // ["Sample phrase is included in this string.", "Another sample phrase."]
