We decided it is better to have a less intelligent search (that does not
match search terms in titles) for some people than a bad-performing
search for everyone.
We will revisit the search performance topic in the next release cycle,
possibly with larger changes around indexing.
Refs #1738, #1741, #1764.
wrap() only adds a table prefix when referencing a column with a table
name (such as `foo.bar`) - when only a single identifier is provided, it
is assumed to be a column name, which does not need a prefix.
Fixes#1659.
The previous approach of joining the posts table into the main search
query was not scaling well. Searches on discuss.flarum.org were taking
~1.5 seconds which – a significant improvement over the pre-beta 8
search, but still not acceptable.
This new approach uses a much more efficient subquery join. Searches
on discuss.flarum.org now take mere milliseconds. The search result
ranking strategy has been further refined as well so that discussions
are ranked by the collective relevance of their posts.
* Improve fulltext gambit
* Only search in visible posts
This change relies on the `visibility-scoping` branch to be merged.
* Change posts table to use InnoDB engine
Doing a JOIN between an InnoDB table (discussions) and a MyISAM table
(posts) is very very (very) bad for performance. FULLTEXT indexes are
fully supported in InnoDB now, and it is a superior engine in every
other way, so there is no longer any reason to be using MyISAM.
* Use ::class
* Only search for comment posts
* Add fulltext index to discussions.title
* Fix migration not working if there is a table prefix
* Update frontend appearance
* Apply fixes from StyleCI
