aid cheng » xi cheng
debt bad » debt based, debt bank, debt a
yang ka » yang fan, yang yao
bad aid » band aid, based aid, brand aid

gt 3 » gt 2, gt _, gt 1
pt 3 » pt 2, pt 1

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang y) OR (yang ka))) OR (yang di))((gt 3) OR (pt 3)) human debt bad aid cheng guan ;~.
• Adding a wildcard symbol may retrieve word variants: ((((yang y) or (yang ka))) or (yang di))((gt 3) or (pt 3)) human debt bad aid cheng guan ;*.
