Filter packages by “date last updated”

[pauloxnet]

What's the problem this feature will solve?
I want to be able to filter packages by “date last updated”.

Describe the solution you'd like
It would be very convenient to have a new filter in the page where to select the amount of time to use to filter by last update date leaving the sorting by relevance.

Additional context
For example I’m searching for libraries with the term “opengraph” and I see 102 projects in the results, but the first ones in the list have not been updated for several years. (e.g. 2012, 2014, 2015, 2018, ...)
https://pypi.org/search/?q=opengraph

I would like to have an easy way to do the same search but only see the packages that have had at least one update in the last 2 years or similar.

An examples of filters we might want to use would be: <number:integer> <scale:(hours|days|weeks|months|years)) (e.g. 3 months, 3 years, 7 days)

Curious doesn't this dropdown get you that?

Beyond that, the majority of the search queries and operators, and boosting settings are here:

The dropdown is limited to sorting by "Relevance" or "Date last updated", but a very recent packages may not be relevant at all, and relevant ones may not have been updated in years.

As I tried to explain above, in my search I want to keep the sorting by "Relevance", but only include in the results packages that have had an update in a certain time frame (e.g. last 2 years).

Beyond that, the majority of the search queries and operators, and boosting settings are here: https://github.com/pypi/warehouse/blob/7194600c2f7cbe88f64a4387f8869cc634036e52/warehouse/search/queries.py

Thanks for pointing me in, I've never seen the warehouse code, but I'll try to look into it.
