@afhammad you have to split it into two queries

first check if tags/selected are empty or not

then do one of two queries

this is kind of a special case you have there

@tonsky with that in mind how do I do the equivalent of an IN query? i.e are any of [1 3] in :card/tags which is {:db/valueType :db.type/ref :db/cardinality :db.cardinality/many}

[:find ?e
 :in $ [?tag-id ...]
 :where [?e :card/tags ?tag-id]]

IN is implicit

ah! i was missing the …. thanks

yep, that’s collection destructuring
