• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung thi que lang. bui trong hoc bang ) OR ( phung thi qua van. doi song co so ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung thi que lang. bui trong hoc bang ) or ( phung thi qua van. doi song co so ))*.
