Re: [TM4J-users] Sorting in Tolog

[Kal A. <ka...@te...>]

Hi Dandan,

The default sorting algorithm is not exactly clever - if you sort a 
variable that binds to TopicMapObjects (like $TYPE binds to Topics in 
your query), then the sort order is by the ID property of the topics.

Are you seeing the results at least grouped together by type (even if 
the types are not necessarily in the order you expect) ? Or are you 
seeing them all mixed up ?

Cheers

Kal
