Perhaps you should try some spelling variations:
"sequence networks. historical survey" » "sequential networks. historical survey", "influence networks. historical survey", "reference networks. historical survey"
"science network. historical survey" » "sciences network. historical survey", "science networks. historical survey", "science work. historical survey"

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: (((("sequence networks. historical survey") OR ("frequency networks. historical survey"))) OR ("science network. historical survey")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"sequence networks. historical survey\") OR (\"frequency networks. historical survey\"))) or (\"science network. historical survey\"))".
• Removing quotes may allow a broader search: (((( sequence networks. historical survey ) OR ( frequency networks. historical survey ))) or ( science network. historical survey )).
• Adding a wildcard symbol may retrieve word variants: (((("sequence networks. historical survey") OR ("frequency networks. historical survey"))) or ("science network. historical survey"))*.
