• If you are trying to use Boolean operators, they must be ALL CAPS: col·leccio ((mfarc OR marcen) OR ((arc OR marc) OR ((arche OR farco) OR arce))) al-andaluz ;~.
• Adding a wildcard symbol may retrieve word variants: col·leccio ((mfarc or marcen) or ((arc or marc) or ((arche or farco) or arce))) al-andaluz ;*.
