In jIO, a complex query can ask a storage server to select, filter, sort, or

For some storages (like localStorage), complex queries can be a powerful tool

some server-side logic should be run to avoid having to request large amount of
documents to run a query on the client. If distant storages are static, an
alternative would be to use an indexStorage with appropriate indices as complex
