Document lastModified, createdDate, docDate meaning

On LinkQ project when we request entity/search for document we can see in the responce several dates:

"lastModified_attr_dt":

"createdDate_attr_dt":

"docDate_attr":

What does each mean?

Which one is related to document creation? What modifications can be done for news to have last modified date?

Source of all the predicates can be tracked down using 

GET /datafusion/api/context/list?includeAll=false

lastModified_attr_dt and createdDate_attr_dt can be used interchangeably. It's essentially when that document gets indexed by solr so it's sensitive to re-indexing. We will be adding an ingest timestamp to make it more reliable in the future.

docDate_attr comes from NFD but it's a string ao Solr date operations will not work on it. NFD sends a copy of an updated article (duplicate) and we do not reconcile the copies in any way.

Does it mean to filter news by time period we can rely on "createdDate_attr_dt"?

Yes. Please let us know if you find any inconsistencies.
