Perhaps you should try some spelling variations:
small estimates » small states, sharp estimates, summary estimates
estimates using » estimation using
klang des » klang der, klarung des, klange das
klage der » lage der, anklage der, anlage der
dong sind » dong sin, dong ping
dong bin » dong sin, dong di, dann bin

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

• Performing a fuzzy search may retrieve terms with similar spellings: klang des ((klage der) OR (klages oder)) small estimates using ((dong bin) or (dong sind)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: klang des ((klage der) OR (klages oder)) small estimates using ((dong bin) OR (dong sind)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "klang des ((klage der) OR (klages oder)) small estimates using ((dong bin) or (dong sind)) ;*".
