您可以使用迭代和递归方法并返回检查结果，并在子节点匹配搜索值时构建新的对象和数组。

function getValue(item) {
    if (Array.isArray(item)) {
        return item.reduce(iterA, undefined);
    }
    if (item && typeof item === 'object') {
        return iterO(item);
    }
    if (typeof item !== 'object' && item.toString().toLowerCase().indexOf(search) !== -1) {
        return item;
    }
}

function iterO(o) {
    var temp = Object.keys(o).reduce(function (r, k) {
            var value = getValue(o[k]);
            if (value) {
                r = r || {};
                r[k] = value;
            }
            return r;
        }, undefined);

    if (temp) {
        Object.keys(o).forEach(function (k) {
            if (!(k in temp)) {
                temp[k] = o[k];
            }
        });
    }
    return temp;
}

function iterA(r, a) {
    var value = getValue(a);
    if (value) {
        r = r || [];
        r.push(value);
    }
    return r;
}

var data = [{ booking_name: "gtec/1101822/lmikdy/ls-rmea/oss11", asset_count: 2, pdg: "Invalid", user_area: "Invalid", deployment_number: "Invalid", spoc: "invalid", release: "Invalid", start_date: "2017-06-12 00:00:00", end_date: "2017-06-16 00:00:00", asset_info: [{ bams_id: "BAMS-1001423507", hostname: "GTVOSS11", status: 10, site_location: "IEAT01 Tipperary", rack_number: "VIRTUAL RACK", rack_u_position: 0, manufacturer: "EMC", model: "VM" }, { bams_id: "BAMS-1001368001", hostname: "None", status: 10, site_location: "IEAT01 Tipperary", rack_number: "VIRTUAL RACK", rack_u_position: 0, manufacturer: "HP", model: "HP BL460C GEN8" }], full_name: "Invalid (invalid)", email_address: "Invalid" }, { booking_name: "gtec/1101822/lmikdy/ls-rmea/oss11", asset_count: 2, pdg: "Invalid", user_area: "Invalid", deployment_number: "Invalid", spoc: "invalid", release: "Invalid", start_date: "2017-06-12 00:00:00", end_date: "2017-06-16 00:00:00", asset_info: [{ bams_id: "BAMS-1001423507", hostname: "GTVOSS11", status: 10, site_location: "IEAT01 Tipperary", rack_number: "VIRTUAL RACK", rack_u_position: 0, manufacturer: "EMC", model: "VM" }], full_name: "Invalid (invalid)", email_address: "Invalid" }],
    search = 'emc',
    result = data.reduce(iterA, undefined);

console.log(result);
