Create search_index_0 to search_index_15 tables and shard each index by
account id. MySQL has no ability to pre-filter fulltext indexes by
another field so this is the best bet for improving performance.
Each fulltest index internally creates 11 sub tables (see
https://dev.mysql.com/doc/refman/8.4/en/innodb-fulltext-index.html) so
actually we have 192 tables in total here.
The search_index table name is generated dynamically based on the
account_id.
Add a single search_index table for full-text search of cards and
comments.
For the search there is a full-text index on the title and content
columns. The board_ids is also included in the table and accessible
board ids are pre-loaded and included in the search query. This allows
us to filter out inaccessible records before joining with other tables.
Right now the search is just using boolean search. This would give us
a bunch of syntax options
(see https://dev.mysql.com/doc/refman/8.4/en/fulltext-boolean.html)
except the search query filters those out.
I've removed the searchable_by method for now - everything is built
on the assumption that there's a single search index table and all data
must fit into it.
Queries are written in SQL, we don't have a SearchIndex ActiveRecord
model. That's because we'll likely want to shard the table and it will
be simpler to just keep with the raw SQL for that.
There's no stemming, highlighting or snippet extraction yet - we are
dumping the full description in the search results.
Data can be reindexed with the search:reindex rake task.
Once the sqlite 'vec0' module was removed from the codebase in
38a7a144 (following the table removal in 875a298f), this migration
became unrunnable. So to make sure we can reconstruct the schema if
necessary by running all the migrations, I'm replacing it with the
creation of an empty table.
Removes the creating status completely as well as the abandoned cards system. It will
always resume drafts if they exist, for a given collection and user.
