Dev Notes

Search

• SQLite supports full-text search via the built-in FTS5 extension, which is enabled by default and loaded in the Elixir Driver. The extension requires building a virtual table that holds the data to be searched. This seems to be akin to a materialized view.
• To have fuzzy search, another extension needs to be loaded. Exqlite recommends using ExSqlean, which in turn uses Sqlean, but the extension is NOT part of the ExSQlean set. Need to investigate with forking and PR.

Queries

• To get the count of records per genre:

  select genre.value, count(genre.value) as c from records, json_each(records.genres) genre group by genre.value order by c desc;
  

• To get the count of records per artist:

  select json_extract(artist.value, '$.name') AS name, count(1) as c from records, json_each(records.artists) artist group by name order by c desc;
  

  Note that this query would fail to disambiguate artists with the same name - can be fixed by using the artist musicbrainz_id.
