【中文标题】搜索字符串数组以找到匹配的单词之一

【英文标题】：Searching through an array of strings to find one of the words matching

【问题描述】：

我试图让我的用户输入一个搜索词，然后返回数组中与他们输入的所有名称匹配的字符串。因此，如果他们在这里输入 clinton，它会找到所有的 clintons，但如果他们搜索 hillary clinton，省略 rodham 中间名，它会返回 hillary，但不会返回 bill 或 chelsea。

const array = ['hillary rodham clinton', 'bill clinton', 'chealsea clinton', 'louise penny', 'amanda litman']

const searchTerm1 = 'hillary clinton' // should return hillary rodham clinton
const searchTerm2 = 'clinton' // should return hillary rodham clinton, bill clinton, chelsea clinton
const searchTerm3 = 'hillary' // should return hillary rodham clinton

【参考方案1】：

假设您的搜索词总是由一个空格分隔，您可以执行以下操作：

const array = ['hillary rodham clinton', 'bill clinton', 'chealsea clinton', 'louise penny', 'amanda litman']

const searchTerm1 = 'hillary clinton' // should return hillary rodham clinton
const searchTerm2 = 'clinton' // should return hillary rodham clinton, bill clinton, chelsea clinton
const searchTerm3 = 'hillary' // should return hillary rodham clinton

let find = (term) => array.filter(item => term.split(' ').every(r => item.split(' ').includes(r)))

console.log(find(searchTerm1))
console.log(find(searchTerm2))
console.log(find(searchTerm3))

【参考方案2】：

您可以使用此功能进行搜索。

function search(searchTerm, array) 
        const words = searchTerm.split(" ");
        let tmpArray = array;
        for (let i = 0; i < words.length; i++) 
            tmpArray = tmpArray.filter(obj => obj.indexOf(words[i]) >= 0);
        
            
        return tmpArray;


const newArray1 = search(searchTerm1, array);
const newArray2 = search(searchTerm2, array);
const newArray3 = search(searchTerm3, array);
