Perhaps you should try some spelling variations:
historical studies » historical survey
sequence networks » frequency networks, sequential networks, influence networks
sciences network » services network
science network » science networks, science 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: ((((((science network) OR (sciences network))) OR (sequence networks))s) OR (((((science network) OR (sciences network))) OR (sequence networks)))). historical studies.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((science network) OR (sciences network))) or (sequence networks))s) or (((((science network) OR (sciences network))) or (sequence networks)))). historical studies".
• Adding a wildcard symbol may retrieve word variants: ((((((science network) OR (sciences network))) or (sequence networks))s) or (((((science network) OR (sciences network))) or (sequence networks)))). historical studies*.
