Perhaps you should try some spelling variations:
research comments » research commons, research contents, research commentary
work research » network research
online bound » online bounded, online around, online rounds
bound search » bounded search, based search
online work » online word, online world, line work

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: (( online bound search document ) OR ( online work research comments ))*.
