Function of IsQuestCompleted

Hey, can anyone tell me what is the function of IsQuestCompleted. Do we put it when we include CBs or other things in the quest in order for HB not to repeat them ?

 

icq is usually paired with hasquest or !hasquest

or !icq

 

hasquest & isquestcompleted = we can turn it in
!hasquest & isquestcompleted = we already did it in the past and turned it in
!hasquest & !isquestcompleted , i use that for quests that are started by items that drop of mobs, if we dont have the quest and we havent done it in the past, grind till the item is there and accept quest
