|| calculates the logical OR of two expressions as in:

|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
- Expression:
<exp1>||<exp2> - Operand: expression (true, false)
Common Usage
Example: find 10 cards or customers' information
find().nodes({@card || @customer}) as n
limit 10
return n{*}
Example: Find 10 cards at level greater than 5 or balance beyond 500,000
find().nodes({@card.balance > 500000 || @card.level > 5}) as n
limit 10
return n{*}
Note: the filter can be put into {@card && (balance > 500000 || level > 5)}, where || has lower precedence than &&, but the parenthesis ( ) can raise its priority.
