number of tables: 6
number of key/value pairs: 7
In the "cache tables and key/values" section, the table name (engine name) is at
first position on the second there is the calculated expire date and on the
third and fourth position the key/value is shown.
About duckduckgo: The *vqd coode* of ddg depends on the query term and therefore
the key is a hash value of the query term (to not to store the raw query term).
In the "properties of ENGINES_CACHE" section all properties of the SQLiteAppl /
ExpireCache and their last modification date are shown::

These properties provide information about the state of the ExpireCache and
control the behavior. For example, the maintenance intervals are controlled by
the last modification date of the LAST_MAINTENANCE property and the hash value
of the password can be used to detect whether the password has been changed (in
this case the DB entries can no longer be decrypted and the entire cache must be
discarded).

Fixes the semantic scholar engine by extracting a ui version token.
BTW: remove html tags from the content.
Author's checklist:
- they are ratelimiting very fast, if you do approx more than 2 requests per
minute, you have to wait some time again...
- they also have an official api at api.semanticscholar.org, but it's ratelimits
are even harder

The Yahoo engine's fetch_traits function has been encountering an error in CI
jobs for several months [1], thus aborting the process for all other engines as
well.
The language selection dialog (which fetch_traits calls) requires an `EuConsent`
cookie. Strangely, the cookie is not needed for searching, which is why the
engine itself still works.
Since Yahoo won't be conquering any new marketplaces in the foreseeable future,
it should be sufficient to hard-implement the list of currently available
languages (`yahoo_languages`).

Re-writes the Mullvad Leta integration to work with the new breaking changes.
Mullvad Leta is a search engine proxy. Currently Leta only offers text search
results not image, news or any other types of search result. Leta acts as a
proxy to Google and Brave search results.
- Remove docstring comments regarding requiring the use of Mullvad VPN, which is
no longer a hard requirement.
- configured two engines: ``mullvadleta`` (uses google) and
``mullvadleta brave`` (uses brave)
- since leta may not provide up-to-date search results, both search engines are
disabled by default.
.. hint::
Leta caches each search for up to 30 days. For example, if you use search
terms like ``news``, contrary to your intention you'll get very old results!
