For Loop Filter

The filter part of a for loop can consist of four parts:

Where

    where e1

e1 is a boolean expression which needs to evaluate to true for the element to be iterated.

Order By

    order by e2 asc/desc

e2 is an expression that needs to produce a primitive type such as String or Int, which will be used to order the elements ascending or descending.

Limit

    limit e3

e3 is an Int expression which will limit the number of elements that get iterated.

Offset

    offset e4

e4 is an Int expression which will offset the starting element of the iteration.

Each of the four parts is optional, but they have to be specified in this order. The filtering is done in the application, so use queries instead of filters to optimize the WebDSL application.
