Support exclusive ranges for numeric metatags. For example, `id:5...10`
is equivalent to `id:>=5 id:<10`. Useful for splitting searches into id
ranges without the endpoints overlapping: id:100...200, id:200...300,
id:300...400.
Support using the same numeric-valued metatag twice in the same search.
Numeric-valued metatags are those taking an integer, float, filesize, or
date argument. Previously using the same metatag twice would cause the
second metatag to overwrite the first metatag.
Examples:
* "id:>5 id:<10"
* "width:>500 width:<1000"
* "date:>2019-01-01 date:<2020-01-01"
Support using quoted values with all metatags. For example: user:"blah blah",
pool:"blah blah", commentary:"blah blah", etc. Things like rating:"safe",
id:"42" also work. Both single and double quotes are supported.
Also make the status: and rating: metatags fully free. Before only
status:deleted and rating:s were free.
Refactor so that all metatags that use parse_helper (which is most
integer-valued metatags) support the special "any" and "none" keywords.
This is mainly for consistency, since it's really only useful for using
width:none and height:none to find for certain old unsupported filetypes
that have null width/height values.
Fold parse_helper_fudged into parse_helper. This is used to make
mpixels:N and filesize:N do an inexact match with a 5% error tolerance.
For example, filesize:1mb is really equivalent to filesize:0.95mb..1.05mb
because an exact filesize:1mb search is unlikely to match anything.
Bug: searching for "filetype:jpg -user:evazion" would negate the
filetype:jpg metatag too. This was because the -user:<name> metatag was
negating the entire cumulative relation instead of just the user:<name>
clause.
Add:
* commentary:true (posts with commentary)
* commentary:false (posts without commentary)
* commentary:translated (posts with translated commentary)
* commentary:untranslated (posts with untranslated commentary)
* commentary:"text" (posts where any commentary field matches "text")
Known issues:
* There's no way to escape the true, false, translated, or
untranslated keywords to do a literal text search for commentaries
containing one of these keywords.
* Negated searches may be slow. Using a left outer join instead of a
subquery would be faster in most cases, but negating it is harder.
* Fix fav:<user> searches to return no results instead of raising a
UserPrivilege error when the user has private favorites.
* Fix fav:<nonexistent_user> raising a UserPrivilege error instead of
returning no results.
* Fix -ordfav:<user> not being supported.
Change favgroup:<name> searches to return no results instead of raising
a UserPrivilege error when an unpermitted user searches for a private
favgroup.
Partial fix for #4389.
Partial fix for #4389.
* Fix invalid username searches returning all posts instead of no posts.
* Fix "user:A user:B" returning results for user:B instead of no results.
* Fix "approver:A approver:B" returning results for approver:B instead of no results.
* Add support for negated -commenter, -noter, -noteupdater, -upvote, -downvote metatags.
* Add support for "any" and "none" values for all username metatags,
including negated metatags that didn't support "any" or "none" before.
* Change noter:any and commenter:any to include posts with deleted notes
or comments. Note that commenter:<username> already included deleted
comments before. This is so that commenter:any has the same behavior
as commenter:<username>
Side effects:
* The data-current-user-is-voter <body> attribute has been removed.
* {{upvote:self}} no longer works. {{upvote:<name>}} should be used instead.
* Support negated wildcards in searches (e.g. "holding -holding_*")
* Raise wildcard limit to matching 25 tags regardless of user level.
* Fix wildcards potentially matching empty tags.
* Fix wildcard tags being sorted by post count only, and therefore not
having a stable ordering when tags have equal post counts.
* Fix sidebar to calculate wildcards tags the same way the search does.
* Add options for changing the order of the modqueue (newest first,
oldest first, highest scoring first, lowest scoring first).
* Change the default order from oldest posts first to most recently
flagged or uploaded posts first.
* Add an order:modqueue metatag to order by most recently flagged or
uploaded in standard searches.
* Change the `disapproval:<reason>` metatag to `disapproved:<reason>`.
* Change `disapproved:<reason>` to show all posts disapproved for a
given reason, not just those disapproved by the current user.
* Allow searching for your own disapprovals with `disapproved:<my_name>`.
* Drop the `disapproved:<any|none>` metatags. `disapproved:any` is
equivalent to `disapproved:<my_name>` and `disapproved:none` is
equivalent to `-disapproved:<my_name>`.
These changes are so that you can search e.g. disapproved:poor_quality
to find all posts disapproved for poor quality.
Add a curated posts page at /explore/posts/curated. Curated posts are
the most favorited posts by contributor-level users (users with
unlimited upload permissions).
Also add an order:curated tag using for use in regular searches.
* Let gold users use upvote:self, downvote:self metatags to search for
their own votes.
* Don't let mods use upvote:<user>, downvote:<user> metatags to see
votes by other users. Only let admins see other users' votes.
* Add vote count to profile page.

There was a recent outage that was caused by the read replica
(yukinoshita.donmai.us) being temporarily unavailable. The pg driver in
rails got hardstuck trying to connect to the replica, which brought down
the whole site. The app servers stopped responding and could only be
brought down with SIGKILL. Even try to boot the rails console didn't
work.
We only really used this to calculate tag counts inside Post.fast_count,
which wasn't really beneficial since the read replica is slower than the
main database.
Stop using the pool_string field internally, but keep maintaining it
until we can drop it later.
* Stop using the pool_string for `pool:<name>` metatag searches.
* Stop using the pool_string in the `Post#pools` method. This is used to
get the list of pools on post show pages.
* Change the source index on posts from `(lower(source) gin_trgm_ops) WHERE source != ''`
to just `(source gin_trgm_ops)`. The WHERE clause prevented the index
from being used in source:<url> searches because we didn't specify
the `source != ''` clause in the search itself. Excluding blank
sources only saved a marginal amount of space anyway. This fixes
timeouts in source:<url> searches and in the bookmarklet (since we do
a source dupe check on the upload page too).
* Also switch from indexing `lower(name)` to `name` on pools and users.
We don't need to lowercase the column because GIN indexes can be used
with both LIKE and ILIKE queries.
* Drop support for `source:pixiv/artist-name` searches. This was a hack
that only worked on old pixiv urls that haven't been used for years.
* Replace the old SourcePattern(lower(source)) index with a trigram index.
Refactor various post_tag_match methods to use subqueries instead of joins.
This simplifies things inside PostQueryBuilder, since now we can assume
we're always dealing with a Post relation, rather than some other table
joined with the posts table.
