DEV: Replace #pluck_first freedom patch with AR #pick in core ()
The #pluck_first freedom patch, first introduced by @danielwaterworth has served us well, and is used widely throughout both core and plugins. It seems to have been a common enough use case that Rails 6 introduced it's own method #pick with the exact same implementation. This allows us to retire the freedom patch and switch over to the built-in ActiveRecord method.

There is no replacement for #pluck_first!, but a quick search shows we are using this in a very limited capacity, and in some cases incorrectly (by assuming a nil return rather than an exception), which can quite easily be replaced with #pick plus some extra handling.

FIX: de-prioritize archived topics ()
Previously due to an error archived topics were more prominent in search
than closed topics.

This amends our internal logic to ensure archived topics are bumped down
the list.

FIX: add support for PG 14 and up ()
Previously to_tsquery would split terms and join with &

In PG 14 terms are split and use <-> which means followed directly by.

In PG 13:

discourse_test=# SELECT to_tsquery('english', '''hello world''');
     to_tsquery
---------------------
 'hello' & 'world'
(1 row)

In PG 14:

discourse_test=# SELECT to_tsquery('english', '''hello world''');
     to_tsquery
---------------------
 'hello' <-> 'world'
(1 row)


Change is very unobtrosive, we simply amend our to_tsquery to behave like
it used to behave and make no use of the `<->` operator


More detail at: https://akorotkov.github.io/blog/2021/05/22/pg-14-query-parsing/

Note that plainto_tsquery used elsewhere in Discourse keeps the exact
same function.

This also corrects a faulty test that was passing by a fluke on older
version of PG

FEATURE: prioritize_exact_search_title_match hidden setting ()
The new `prioritize_exact_search_match` can be used to force the search
algorithm to prioritize exact term matches in title when ranking results.

This is scoped narrowly to titles for cases such as a topic titled:

"organisation chart" and a search of "org chart".

If we scoped this wider, all discussion about "org chart" would float to
the top and leave a very common title de-prioritized.

This is a hidden site setting and it has some performance impact due
to double ranking.

That said, performance impact is somewhat mitigated cause ranking on
title alone is a very cheap operation.

FEATURE: hidden site setting to disable search prefix matching ()
Many users seems surprised by prefix matching in search leading to
unexpected results.

Over the years we always would return results starting with a search term
and not expect exact matches.

Meaning a search for `abra` would find `abracadabra`

This introduces the Site Setting `enable_search_prefix_matching` which
defaults to true. (behavior unchanged)

We plan to experiment on select sites with exact matches to see if the
results are less surprising

FIX: Replace all quote-like unicodes with quotes ()
If unaccent is called with quote-like Unicode characters then it can
generate invalid queries because some of the transformed quotes by
unaccent are not escaped and to_tsquery fails because of bad input.

This commits replaces more quote-like Unicode characters before
unaccent is called.

FIX: Make sure generated tsqueries are valid ()
The tsquery used for searching is generated using both functions from
Ruby and Postgresql (for example, unaccent function). Depending on the
term used, it generated an invalid tsquery. For example "can’t"
generated "''can''t''" instead of "''can''''t''".

FIX: Limits for PM and group header search ()
When searching for PMs or PMs in a group inbox, results in the header search were not being limited to 5 with a "More" link to the full page search. This PR fixes that.

It also simplifies the logic and updates the search API docs to include recently added `in:messages` and `group_messages:groupname` options.

FEATURE: Promote polymorphic bookmarks to default and migrate ()
This commit migrates all bookmarks to be polymorphic (using the
bookmarkable_id and bookmarkable_type) columns. It also deletes
all the old code guarded behind the use_polymorphic_bookmarks setting
and changes that setting to true for all sites and by default for
the sake of plugins.

No data is deleted in the migrations, the old post_id and for_topic
columns for bookmarks will be dropped later on.

FEATURE: Polymorphic bookmarks pt. 3 (reminders, imports, exports, refactors) ()
A bit of a mixed bag, this addresses several edge areas of bookmarks and makes them compatible with polymorphic bookmarks (hidden behind the `use_polymorphic_bookmarks` site setting). The main ones are:

* ExportUserArchive compatibility
* SyncTopicUserBookmarked job compatibility
* Sending different notifications for the bookmark reminders based on the bookmarkable type
* Import scripts compatibility
* BookmarkReminderNotificationHandler compatibility

This PR also refactors the `register_bookmarkable` API so it accepts a class descended from a `BaseBookmarkable` class instead. This was done because we kept having to add more and more lambdas/properties inline and it was very messy, so a factory pattern is cleaner. The classes can be tested independently as well.

Some later PRs will address some other areas like the discourse narrative bot, advanced search, reports, and the .ics endpoint for bookmarks.

FIX: Use the same mode for chinese search when indexing and querying. ()
The `白名单` term becomes `名单 白名单` after it is processed by
cppjieba in :query mode. However, `白名单` is not tokenized as such by cppjieba when it
appears in a string of text. Therefore, this may lead to failed matches as
the search data generated while indexing may not contain all of the
terms generated by :query mode. We've decided to maintain parity for now
such that both indexing and querying uses the same :mix mode. This may
lead to less accurate search but our plan is to properly support CJK
search in the future.

PERF: Optimize search in private messages query ()
* PERF: Remove JOIN on categories for PM search

JOIN on categories is not needed when searchin in private messages as
PMs are not categorized.

* DEV: Use == for string comparison

* PERF: Optimize query for allowed topic groups

There was a query that checked for all topics a user or their groups
were allowed to see. This used UNION between topic_allowed_users and
topic_allowed_groups which was very inefficient. That was replaced with
a OR condition that checks in either tables more efficiently.

DEV: Remove useless ordering when searching within a topic. ()
Searching within a topic currently does not make use of PG search and
we're simply doing an `ilike` against the post raw. Furthermore,
`Post#post_number` is already unique within a topic so the other
ordering will never ever be used. This change simply makes the query
cleaner to read.

Prior to this change, we had weights for very_high, high, low and

use for `very_high/high` and `very_low/low` pair was hard to explain.
This change makes it such that `very_high` search priority will always
ensure that the posts are ranked at the top while `very_low` search
priority will ensure that the posts are ranked at the very bottom.

PERF: avoid lookbehinds when indexing search ()
* PERF: avoid lookbehinds when indexing search

Previously we used a `EmailCook.url_regexp` this regex used lookbehinds

Unfortunately certain strings could lead to pathological behavior causing
CPU to skyrocket and regex replace to take a very very long time.

EmailCook still needs a fix, but it is less urgent cause it already splits
to single lines. That said we will correct that as well in a seperate PR.

New implementation is far more naive and relies on the extra spaces search
indexer inserts.
