Hi Tony > Do you think this is a bug?
It’s a subtle difference in the handling of missing fields between two slightly different formulations. Using the advanced search “filter” tab on tw.com <http://tw.com/>, [{HelloThere!!missing}] returns 1 result (an empty string), while [[HelloThere]get[missing]] returns zero results. The history is that the transclusion syntax came first, at some point we realised that not being able to distinguish between a missing field and a blank field was a problem, and so we “fixed” it by adding the new get operator (we couldn’t change the behaviour of the transclusion syntax without breaking backwards compatibility).
