twitter search node using operator "until"


I was trying to use Twitter Search node and the following query "@KNIME until:2015-01-31" always returned empty data table. The Twitter Search node returned some rows if I remove the "until:2015-01-31".

Am I doing something wrong or is it a bug?



I tried out the query with and without the "until". Without it I only get Tweets starting from 2015-03-04. If I now use "until:2015-03-10" I get tweets ranging between 2015-03-04 and 2015-03-09. So the operator seems to work correctly. The Twitter API simply doesn't return older Tweets (in this case). Unfortunatly there is no public information how Twitter selects the Tweets that are available via the (free and limited) API.
