Condition groups are always concatenated to each other by using OR logic. To start a new condition group, call IWMPQuery::beginNextGroup.

Compound queries using IWMPQuery are not case sensitive.

A list of values for the bstrAttribute parameter can be found in the Alphabetical Attribute Reference section.
