Using mix of AND and OR clause in sails and waterline

Question

How can I use OR and AND clause in Sailsjs and its ORM Waterline? For example I have a table of books

 _______________________________________
| book_name |          


        

Answer 1

The following query should also work:

const books = yield Book.find().where({
  author: 'Author-1',
  or: [{
    free: true,
  }, {
    public: true,
  }],
});

Answer 2

For doing so we can use the where api of Waterline, following is an example

Book.find().where(  { or : [ { free  : true }, {   public: true  } ] })
            .where( { author : "Author-1" }  )
            .exec( function (err, books) {
            //Books will be an array containing all the books that matches this criteria
            //Some code here
    }

Answer 3

  let booksResult=await Book.find().
                        where({author: "Author-1", 
                           or: [{ free: true  }, { public: true  }]
                        });
