I could not get more than 6 months of data from GDELT gkg table.
For example, this query returns only results from 19 Feb 2015:
SELECT Date, SourceCommonName, DocumentIdentifier FROM [gdelt-bq:gdeltv2.gkg]
where (date < 20150220000000 and locations like "%Israel%" and
SourceCommonName = "cnn.com")
The same query for date < 20150219000000 returns no results
How can I get older results/ why aren't older results returned?
