@ -428,6 +428,13 @@ Comparison operators (all binary):
- `LE`: less or equal - `LE`: less or equal
- `LT`: less than - `LT`: less than
Pattern operator:
- `LIKE`: specifies pattern for an attribute. Uses as a wildcard symbol `*`.
- `... ATTR LIKE "VAL"` - the behaviour is equal to `EQ`
- `... ATTR LIKE "VAL*"` - matches all which starts with `VAL`
- `... ATTR LIKE "*VAL"` - matches all which ends with `VAL`
- `... ATTR LIKE "*VAL*"` - matches all which contains `VAL`
Logical operators: Logical operators:
- `NOT`: negation (unary) - `NOT`: negation (unary)
- `AND`: conjunction (binary) - `AND`: conjunction (binary)
