The query takes the form of {propertyName}={value}.

For greater-than, greater-than-or-equal, less-than, and less-than-or-equal-to. In order, the operators are: gt, gte, lt, and lte.

Multiple query clauses can be specified, separated by ampersands (;) for AND queries.

Sub-properties can be accessed by separating them with a dot. At this time, you can only filter on the id sub-property.

You can query strings using the wildcard (%) operator.

You can query with child elements by applying the dot notation (e.g. ?lines.description="abc").
