尝试在sequelize db中使用原始sql，不确定为什么不起作用。
下面是带有查询的控制器：

const db = require("../../models");
const Book = db.book;
const User = db.user;
const Sequelize = require('sequelize');
const { sequelize } = require('../../models/index.js');

exports.getAllBooks = async (req, res) => {
    console.log('query: ', req.query);
    let books;
    if (Object.keys(req.query).length === 0) {
        books = await Book.findAll();
        res.json(books);
    } else {
        [books, metadata] = await sequelize.query(`
            SELECT ('title')
            FROM Book
            WHERE searchable @@ to_tsquery(${req.query});
        `);
        res.json(books);
    }
};
