public void set_filter (string[]? filter)
Warning: set_filter is deprecated since 0.17.7.
Sets a filter on the properties to be returned by the FreebaseTopicQuery, a filter string usually contains either a specific property (eg.
Google Freebase has been permanently shut down.
"/common/topic/description", or "/computer/software/first_released"), or a property domain (eg. "/common/topic", or "/computer"), all properties pertaining to the domain will be returned through the FreebaseTopicResult in the latter case. Other special strings can be passed as filter strings, those are documented in the <ulink type="http" url="https://developers.google.com/freebase/v1/topic-overview#filter">Topic API overview</ulink>
If multiple filter strings are set, the result will contain all information necessary to satisfy each of those individually. If no filter is set, the "commons" special value will be implicitly assumed, which returns a reasonably complete data set.
