Refines a query to match items whose specified property value is within a specified range.
The between()
method refines this query to only match items where the value of the specified property is
greater than or equal to rangeStart
and less than rangeEnd
.
It only matches values of the same type. For example, a number value stored as a String type does not match the same number stored as a Number type.
If a property contains a number as a String, that value is compared alphabetically and not numerically. Items that do not have a value for the specified property are ranked lowest.
The following types of properties can be compared:
"A"
and "M"
are between "A"
and "Z"
, but "a"
, "m"
, "z"
and "Z"
are not."A"
, "M"
, "Z"
, and "a"
are between "A"
and "z"
, but "z"
is not.
Field whose value is compared with rangeStart and rangeEnd.
Starting value of the range to match.
Ending value of the range to match.
