Articles published by the city of Catania. select NomeArticolo, dataArticolo from (select expand(in('pubblicatoIn')) from citta where nomeCitta = "Catania") ----+------+-------------------+------------------- # |@CLASS|NomeArticolo |dataArticolo ----+------+-------------------+------------------- 0 |null |Onde Gravitazionali|2016-02-01 00:00:00 1 |null |Super Magnete |2015-03-05 00:00:00 ----+------+-------------------+------------------- 2) Le citta che hanno pubblicato almeno due articoli. Cities that have published at least two articles select nomeCitta from citta where in('pubblicatoIn').size() > 1 ----+------+--------- # |@CLASS|nomeCitta ----+------+--------- 0 |null |Catania 1 |null |Milano ----+------+--------- 3) articoli pubblicati da milano che sono inerenti alla 'fusione'. published by milano that are inherent to the 'fusion' select NomeArticolo from ArticoloScentifico where NomeArticolo lucene 'fusione*' ----+------+---------------- # |@CLASS|NomeArticolo ----+------+---------------- 0 |null |Fusione a freddo ----+------+---------------- Vedo che il tuo DB รจ strutturato in maniera divera :) I see your DB is structured differently.
