# Returns [DossierProjection(dossier, columns)] ordered by dossiers_ids
# and the columns orderd by fields.
#
# It tries to be fast by using `pluck` (or at least `select`)
# to avoid deserializing entire records.
#
# It stores its intermediary queries results in an hash in the corresponding field.
# ex: field_email[:id_value_h] = { dossier_id_1: email_1, dossier_id_3: email_3 }
#
# Those hashes are needed because:
# - the order of the intermediary query results are unknown
# - some values can be missing (if a revision added or removed them)
