if set until date kepp in mind the documentation

returns tweets generated before given date. date should formatted yyyy-mm-dd. keep in mind search index may not go far date specify here.

and too

before getting involved, it’s important know search api focused on relevance , not completeness. means tweets , users may missing search results. if want match completeness should consider using streaming api instead.

so, if set until date old 0 tweets, in other hand if set since date old tweets few past days in console.
