Logical Operators
and and or combine conditions inside a filter.
AND
mydb.users[status = "active" and country = "IN"]
Only rows that match both conditions.
OR
mydb.orders[status = "open" or status = "partial"]
Rows that match either.
Mixing
mydb.users[
(country = "IN" or country = "US")
and age >= 18
]
Use parentheses to control precedence — same rules as SQL/most languages: and binds tighter than or, but explicit parens always win.
Reading tip
The filter inside [ ... ] is a single boolean expression. Anything that evaluates to "true" for a row keeps that row.
Performance note
Push-down to indexes works for simple = + and/or combinations. More exotic patterns (mixing comparisons with or, nested filters across relations) fall back to in-memory evaluation. See the Optimizer concept page.
