11  * Workflow Query.
12  * A workflow expression-based query is constructed by specifying a number of expressions in the query.
13  * Currently queries can only have one operator act on them. Either the expressions are either evaluated
14  * with an OR, whereby the first expression that passes results in inclusion of a result, or with an AND,
15  * whereby all expressions must return true for a result to be included.
