      And

      && calculates the logical AND of two expressions as in:

      expression1 expression2 Result
      0 0 0
      0 1 0
      1 0 0
      1 1 1

      Common Usage

      Example: find 10 cards whose balances are over 500,000

      find().nodes({@card && balance > 500000}) as n
      limit 10
      return n{*}
      

      Analysis: this filter is a separated form from {@card.balance > 500000}, see Schema Filter &.

      Example: find 10 cards whose balances are greater than 500,000 and whose levels are less than 3.

      find().nodes({@card.balance > 500000 && level < 3}) as n
      limit 10
      return n{*}
