JavaScript：遍历多维数组并提取多个搜索值

Question

我想做的事：

使用多个搜索字符串搜索多维数组。

我目前正在做的示例：

var multiArray = [['Apples and pears', 'tuna salad'],['bananas tuna'],['the colour blue']];

var singleArray = [];

var match_array = [];

// Turn multiple arrays into one big one
    for (var i = 0; i < multiArray.length; i++) {

        for (var x = 0; x < multiArray[i].length; x++) {

            singleArray.push(multiArray[i][x]);
    }
}

// Create a new array from matched strings

function find_match(to_match) {

    for (var i in singleArray) {

        if (singleArray[i].indexOf(to_match)!= -1)

        match_array.push(singleArray[i]);
    }

    return (match_array.length === 0 ? null : match_array);

}

// Find matching terms for match_array
find_match('tuna');
find_match('the');

alert(match_array);

问题：

1. 显然这是一种杂乱无章的做法。怎么会这样 精简（即直接搜索multiArray 而不是使用 多个find_match函数）？

2. 我怎样才能只得到精确的字符串匹配，最好不破坏多维数组？

3. 您对通过海量搜索有何想法 多维数组？

你想要这样的东西吗？

var multiArray = [['Foo', 'Bar'],['Foo'],['Bar']];

var singleArray = [];

var match_array = [];

// Turn multiple arrays into one big one
for (var i = 0; i < multiArray.length; i++) {
    for (var x = 0; x < multiArray[i].length; x++) {
        singleArray.push(multiArray[i][x]);
    }
}

// Create a new array from matched strings
function find_match(to_match, where_search) {

    for (var j in where_search) {
        if(where_search[j] instanceof Array){
           find_match(to_match, where_search[j]);

        }else{
            for (var i in to_match) {
                if (where_search[j].indexOf(to_match[i]) ==0 && 
                    where_search[j].length == to_match[i].length)
                    match_array.push(where_search[j]);
            }
        }
    }

    return (where_search.length === 0 ? null : match_array);

}

// Find matching terms for match_array
find_match(['Foo', 'Bar'],multiArray);

alert(match_array);
