Zerochan not showing/using all keywords available

[RBNXI]

When trying to get all keywords of a single post, for example https://www.zerochan.net/3738878, with -K, it shows all the keywords it has, included date, which is what I need.
But if you use a search url like https://www.zerochan.net/Nekomata+Okayu, it shows only a few keywords, and thus, when trying to download for example all the posts of the current day with a filter, it says "NameError: name 'date' is not defined" even though the posts do have a date keyword and it's shown when passed individually.
This is because the download url of every post when trying to download all the posts in a search query are converted to https://static.zerochan.net/, and that url doesn't have the keywords that https://www.zerochan.net/ has.
So I would like this to be fixed, either by having all the necessary keywords for https://static.zerochan.net too, or by using the https://www.zerochan.net keywords for every https://static.zerochan.net/ url.

Single post and search results use different data extraction strategies while also trying to use the least amount of HTTP requests possible, hence the difference.

The latest release now has a metadata option that uses 1-2 more HTTP requests per post to grab all the possible metadata.
