This collections is > transformed to {{SortedSet(1, 2, 3)}} because IndexQuery provides to user > sorted result. > # When IN applies on first indexed field - IN(A0, A1) for index (A, B) - it > converts to multiple {{eq}} operations are joint with OR operation: > {{{}EQ(A0) or EQ(A1){}}}. > # Other range criteria for other fields are applied to every such separate > operation: > {{IN(A0, A1) and GT(B)}} converts to {{{}(EQ(A0) and GT(B)) or (EQ(A1) and > GT(B)){}}}. > # When IN applies to non-leading indexed field - IN(B0, B1) for index (A, B) > - it works like a filter for prepared range: > {{GTE(A) and IN(B0, B1)}} converts to range {{[[A, B0]; [A, B1]]}} and every > cache entry within this range is checked for being included to SortedSet(B0, > B1). -- This message was sent by Atlassian Jira (v8.20.10#820010)
