Answer 1

I have done as following

   const Op = Sequelize.Op;


    const filter = {
      [Op.and]: [{
        [Op.or]:[
          {
            'params.medium': {
              [Op.regexp]: 'Hindi'
            }
          },
          {
            'params.medium': {
              [Op.regexp]: 'English'
            }
          }
        ],
      },
      {
        [Op.or]:[
          {
            'params.subject': {
              [Op.regexp]: 'Hindi'
            }
          },
          {
            'params.subject': {
              [Op.regexp]: 'Science'
            }
          }
        ],
      }
    ]};

    model.findAll({
        where: {
          ...filter
        }
   )};

Please suggest if any better solution.
