h2. Backend https://www.postgresql.org/docs/9.5/functions-json.html <pre> arvados_development=# select '{"a":["foo","bar"]}'::jsonb @> '{"a":["bar"]}'::jsonb; ?column? ---------- t </pre> So jsonb subset match works if you know the key and are looking for an exact match on the value. It looks like an arvados filter of @[["properties.a", "=", ["bar"]]@ might already work by since it uses @@>@ in the implementation. Although that's arguably a bug since the expectation is to get an exact match. Using @[["properties.a", "in", ["bar"]]@ makes more sense, and also looks like it would work. h2. Frontend UI ???
