Perhaps you should try some spelling variations:
gain yang » dan yang, daun yang, tan yang
wang dan » wang yan, wang ban, wang yidan
dan data » can data, dan dana, dn data
yi chang » ii chang, ying chang, jin chang
yi dang » yi gang
yi yang » yin yang, yi gang, yu yang
data n » data 1, data 2, data new
n gain » _ gain, run gain

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang dan data n gain yang ((((yi dang) OR (yi yang))) or (yi chang)) (hai or hadi) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang dan data n gain yang ((((yi dang) OR (yi yang))) OR (yi chang)) (hai OR hadi) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang dan data n gain yang ((((yi dang) OR (yi yang))) or (yi chang)) (hai or hadi) ;".
• Adding a wildcard symbol may retrieve word variants: wang dan data n gain yang ((((yi dang) OR (yi yang))) or (yi chang)) (hai or hadi) ;*.
