le( )

Refines a query to match items where the specified property is less than or equal to the specified value.

The le() function refines a OperationsQueryBuilder to match only items where the value of the specified propertyName is less than or equal to the specified value. le() matches only values of the same type. For example, 0 stored as a number doesn't match '0' stored as a string. If a property contains a number stored as a string (for example, '0'), that value is compared alphabetically and not numerically. If a property doesn't have a value, that value is ranked lowest. The following types of properties can be compared:

• Number: Compares numerically.
• Date: Compares JavaScript Date objects.
• String: Compares lexicographically, so 'ABC' is less than 'abc'.
