Perhaps you should try some spelling variations:
trigger first » trigger lists
how trigger » shows trigger, lhcb trigger, muon trigger
things were » things here, things we, things work
han change » than change, can change, han chang
dong bin » dong sin, dong di
dort hin » dort bin, dort ii, dort von

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

• If you are trying to use Boolean operators, they must be ALL CAPS: han change how trigger first things were ((((dann bin) OR (dong bin))) OR (dort hin)) ;~.
• Adding a wildcard symbol may retrieve word variants: han change how trigger first things were ((((dann bin) or (dong bin))) or (dort hin)) ;*.
