Specifying time range for research

[yathaarthmagi]

Is your feature request related to a problem? Please describe.
Currently it is not possible to limit the research over a time range (say "1 week", that is, the sources and references for the report should be within the specified time range.

Describe the solution you'd like
Most of the search engines allow us to specify a time range, maybe expose that so all the searches are within the time range in a deterministic way.

Describe alternatives you've considered
Performing the time ranged search myself, and providing those documents for a local documents/hybrid research.
