a hash makes sense for dates, but probably not for categories (more than one) or search,
maybe saving state to query params would be better? (but uglier) @HazAT

[Shubhdeep12]

yes, ideally we should add params for both dates and categories(comma separated ids of categories) in the URL.

this is done
