heat gain » health gain, health gains, wheat grains
kang han » kang chen, kong hang, zhang han
run pain » run gain

• If you are trying to use Boolean operators, they must be ALL CAPS: yang kang han ((heat gain) OR (run pain)) yang ((((xi zhang) OR (xiao zhang))) OR (xi kang)) hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang kang han ((heat gain) or (run pain)) yang ((((xi zhang) OR (xiao zhang))) or (xi kang)) hai ;*".
